Is the Bland-Altman plot method useful without inferences for accuracy, precision, and agreement?

ABSTRACT OBJECTIVE This study aims to propose a comprehensive alternative to the Bland-Altman plot method, addressing its limitations and providing a statistical framework for evaluating the equivalences of measurement techniques. This involves introducing an innovative three-step approach for assessing accuracy, precision, and agreement between techniques, which enhances objectivity in equivalence assessment. Additionally, the development of an R package that is easy to use enables researchers to efficiently analyze and interpret technique equivalences. METHODS Inferential statistics support for equivalence between measurement techniques was proposed in three nested tests. These were based on structural regressions with the goal to assess the equivalence of structural means (accuracy), the equivalence of structural variances (precision), and concordance with the structural bisector line (agreement in measurements obtained from the same subject), using analytical methods and robust approach by bootstrapping. To promote better understanding, graphical outputs following Bland and Altman's principles were also implemented. RESULTS The performance of this method was shown and confronted by five data sets from previously published articles that used Bland and Altman's method. One case demonstrated strict equivalence, three cases showed partial equivalence, and one showed poor equivalence. The developed R package containing open codes and data are available for free and with installation instructions at Harvard Dataverse at https://doi.org/10.7910/DVN/AGJPZH. CONCLUSION Although easy to communicate, the widely cited and applied Bland and Altman plot method is often misinterpreted, since it lacks suitable inferential statistical support. Common alternatives, such as Pearson's correlation or ordinal least-square linear regression, also fail to locate the weakness of each measurement technique. It may be possible to test whether two techniques have full equivalence by preserving graphical communication, in accordance with Bland and Altman's principles, but also adding robust and suitable inferential statistics. Decomposing equivalence into three features (accuracy, precision, and agreement) helps to locate the sources of the problem when fixing a new technique.

Validez de apariencia y racionalidad de una metodología para estudiar la causalidad en salud / Appearance and rational validity of a methodology to study causality in health

Introducción: Es objetivo fundamental de la medicina, determinar las causas que producen las enfermedades; para llevar a cabo este estudio, a finales del siglo XX se emplearon técnicas estadísticas multivariadas confiables en el análisis simultáneo de diferentes variables independientes sobre un desenlace. Objetivo: Determinar la aplicación de la validez racional y de apariencia en la metodología empleada para el estudio de la causalidad en salud. Métodos: Para evaluar si la metodología se correspondía con los requerimientos de la investigación, se aplicó la validez de apariencia para valorar los resultados obtenidos en su aplicación, específicamente, si las reglas reflejan verazmente, lo que ocurre en la práctica médica, mediante el empleo de la validez racional. Resultados: Los usuarios potenciales de la metodología la consideraron aceptable en los aspectos medidos sobre la regresión logística binaria. El mayor porcentaje de las reglas analizadas está en correspondencia con lo planteado en la literatura, pocas plantean aspectos que no se dan necesariamente en la práctica médica, pero tampoco se contradicen con la literatura. Los resultados de la validez de apariencia no fueron favorables, pues la metodología no había sido empleada antes en el contexto. En cuanto a la validez racional, se verificó un alto porcentaje de correspondencia entre lo planteado por las reglas y la literatura. Es importante tener en cuenta, que el hallazgo de algo conocido reafirma la validez de esa regla. Conclusiones: Las reglas obtenidas de la aplicación de la metodología reflejan, en general, lo que ocurre en la práctica médica.

Introduction: the fundamental objective of medicine is to determine the causes that produce diseases. At the end of the 20th century, multivariate statistical techniques were used as reliable in the simultaneous analysis of different independent variables on an outcome. Objective: to determine the application of appearance and rational validity of a methodology to study causality in health. Methods: to evaluate whether the methodology corresponded to the research requirements, appearance validity was applied to assess the results obtained in its application, specifically, if the rules accurately reflect what happens in medical practice, through the use of rational validity. Results: the potential users of the methodology considered it acceptable in the measured aspects of the binary logistic regression. The highest percentage of the rules analyzed is in correspondence with what is stated in the literature; few raise aspects that do not necessarily occur in medical practice, but they do not contradict the literature either. The results of face validity were not favourable, since the methodology had not been used before in the context. A high percentage of correspondence regarding rational validity was verified between what was stated by the rules and the literature. It is important to note that finding something known reaffirms the validity of that rule. Conclusions: the rules obtained from the application of the methodology reflect, in general, what happens in medical practice.

Confessions of an Ayurveda professor

In this essay, I narrate my experiences of teaching Ayurveda physiology through an approach that involved laborious re-interpretation of ancient literature using the recent advances in the field of medical physiology. Though this approach made the ancient concepts and theories appear modern and relevant, it did not contribute much except for apparently reducing cognitive dissonance among students. I cite examples describing the processes of formation of shukra (semen) and rakta (blood) to show how we often overinterpret Ayurveda concepts to make them sound rational by proposing ad hoc conjectures. I illustrate why my previous writings were faulty by applying the falsification principle proposed by Karl Popper. I further explain how this approach made these concepts only verifiable but not refutable, and hence, non-falsifiable. I argue that instead of using such re-interpretation to prove obsolete concepts, they can be dropped altogether from the curricula of Ayurveda programmes. There is a need to develop a reliable method to identify such outdated content.

Tamanho do efeito em estudos observacionais na área de Saúde Bucal Coletiva: importância, cálculo e interpretação / Size effect in observational studies in Public Oral Health: importance, calculation and interpretation

Resumo O objetivo deste estudo foi analisar a literatura científica da área de saúde bucal coletiva quanto ao cálculo, apresentação e discussão do tamanho do efeito em estudos observacionais. A literatura cientifica na área (2015 a 2019) foi analisada quanto: a) informações gerais (periódico e diretrizes aos autores, número de variáveis e desfechos), b) objetivo e coerência com o cálculo amostral apresentado; c) tamanho do efeito (apresentação, medida utilizada e coerência com a discussão dos dados e conclusão). Foram analisados 123 artigos, de 66 periódicos. A maioria dos artigos avaliados apresenta um único desfecho (74%) e não menciona a realização de cálculo amostral (69,9%). Dentre os que realizaram, para 70,3% havia coerência entre o cálculo amostral utilizado e o objetivo. Apenas 3,3% dos artigos mencionam o termo tamanho do efeito e 24,4% não o consideram na discussão dos resultados, apesar de terem calculado. A regressão logística foi a metodologia estatística mais utilizada (98,4%) e o Odds Ratio a medida de tamanho do efeito mais utilizada (94,3%), embora não tenha sido citada e discutida como uma medida de tamanho do efeito na maioria dos estudos (96,7%). Os pesquisadores, em sua maioria, restringiram a discussão dos resultados apenas à significância estatística encontrada nas associações testadas.

Abstract The objective of this study was to analyze the scientific literature in public oral health regarding calculation, presentation, and discussion of the effect size in observational studies. The scientific literature (2015 to 2019) was analyzed regarding: a) general information (journal and guidelines to authors, number of variables and outcomes), b) objective and consistency with sample calculation presentation; c) effect size (presentation, measure used and consistency with data discussion and conclusion). A total of 123 articles from 66 journals were analyzed. Most articles analyzed presented a single outcome (74%) and did not mention sample size calculation (69.9%). Among those who did, 70.3% showed consistency between sample calculation used and the objective. Only 3.3% of articles mentioned the term effect size and 24.4% did not consider that in the discussion of results, despite showing effect size calculation. Logistic regression was the most commonly used statistical methodology (98.4%) and Odds Ratio was the most commonly used effect size measure (94.3%), although it was not cited and discussed as an effect size measure in most studies (96.7%). It could be concluded that most researchers restrict the discussion of their results only to the statistical significance found in associations under study.

Afasias e construção de sentido: estudo com foco em história em quadrinhos / Aphasia and construction of meaning: study focused on comic strips

RESUMO Objetivo observar, na linguagem em afasia de sujeitos adultos, a constituição de sentidos, considerando a (re)organização enunciativa na leitura e na escrita. Métodos pesquisa qualitativa com método aplicado e exploratório e perspectiva de análise enunciativa sobre a linguagem, tendo as noções de forma e sentido como base analítica. Foi realizada uma atividade com três sujeitos com afasia (Bir, Cr e Aul), integrantes do Grupo Interdisciplinar de Convivência (GIC), formado por participantes com e sem afasia. Tal atividade consistiu em (re)organizar quadrinhos de uma história, visando constituir sentido, uma vez que a leitura/escrita de textos são habilidades comumente comprometidas nas afasias. Resultados a categoria de tempo crônico mostra-se fundante para elaboração das narrativas dos sujeitos com afasia. Entretanto, eles encontraram formas distintas de sustentação de sentidos, mas sempre atrelados a experiências provenientes da relação entre homem e mundo. Conclusão as narrativas foram organizadas/construídas pelos participantes, tendo por base as imagens (base formal) - uma vez comprometida a habilidade de leitura de textos verbais. Bir, Cr e Aul usaram o tempo crônico como eixo organizacional de suas narrativas e suas histórias em quadrinhos, demonstrando que promovem leitura e escrita ao se considerar o viés enunciativo de análise da linguagem.

ABSTRACT Purpose to observe , in the language of aphasic adult subjects, the constitution of meanings, considering the enunciative (re)organization in reading and writing. Methods qualitative research with applied and exploratory methods and a perspective of enunciative analysis on language, using the notions of form and meaning as analytical base. From an activity performed by three subjects with aphasia (Bir, Cr and Aul), members of the Interdisciplinary Coexistence Group (GIC), formed by participants with and without aphasia, which constituted of (re)organizing the panels (frames) of a comic strip, in order to constitute meaning - since the reading/writing of texts are skills that are commonly affected in aphasia. Results the chronic time category shows itself to be fundamental for the elaboration of the narratives of the subjects with aphasia, however they found different ways of sustaining meanings, but always linked to experiences arising from the relationship between man and world. Conclusion the narratives were organized/constructed by the participants, having the images as a base (formal base) - since the ability to read verbal texts is impaired. Bir, Cr and Aul used chronic time as an organizational axis of their narratives and their comic strips show that these subjects with aphasia promote reading and writing when considering enunciative bias of language analysis.

Elastografia por cisalhamento (shear wave) para placas ateroscleróticas carotídeas extracranianas: princípios técnicos e como realizar / Shear wave elastography for extracranial carotid atherosclerotic plaques: technical principles and how to do it

Resumo Na esteira de estudos direcionados à placa aterosclerótica e em busca de variáveis quantificáveis que adicionem informações à tomada de decisão terapêutica, a avaliação a partir de elastografia shear wave (SWE) se apresenta como alternativa reprodutível e promissora. Utilizamos um único aparelho Logiq S8 (General Electric, Boston, Massachusetts, Estados Unidos) com um transdutor linear multifrequencial 8,5-11 MHz em 10 MHz em corte longitudinal. Consideramos critérios relevantes para a aquisição de imagem: adequada insonação longitudinal, diferenciação do complexo médio-intimal, delineamento de túnicas adventícias proximal e distal, lúmen vascular, boa visualização da placa aterosclerótica, ciclo em diástole ventricular e ausência de alterações incongruentes. A SWE é um método emergente e extremamente promissor no contexto da avaliação de placas carotídeas, podendo contribuir no futuro para a tomada de decisão terapêutica baseada em características relativas à placa aterosclerótica de forma reprodutível entre aparelhos e examinadores.

Abstract In the wake of studies targeting atherosclerotic plaques and searching for quantifiable variables that contribute additional information to therapeutic decision-making, plaque assessment using Shear Wave Elastography (SWE) is emerging as a reproducible and promising alternative. We used a single Logiq S8 device (General Electric, Boston, Massachusetts, United States) with an 8.5-11MHz multifrequency linear transducer at 10MHz in longitudinal section. We considered relevant criteria for image acquisition: adequate longitudinal insonation, differentiation of the intima-media complex, delineation of proximal and distal tunica adventitia and the vascular lumen, good visualization of the atherosclerotic plaque, cardiac cycle in ventricular diastole, and absence of incongruous changes. SWE is an emerging and extremely promising method for assessment of carotid plaques that may contribute to therapeutic decision-making based on characteristics related to the atherosclerotic plaque, with inter-device and inter-examiner reproducibility.

Pós-processamento da mediana de escala de cinza (GSM), posterização e remapeamento de cores para ultrassonografia de carótidas / Grayscale median (GSM) post-processing, posterizing, and color mapping for carotid ultrasound

Resumo Fatores relativos à placa aterosclerótica podem indicar instabilidade como ulcerações, hemorragias intraplaca, núcleo lipídico, capa fibrosa delgada ou irregular e inflamação. A mediana de escala de cinza (GSM, de greyscale median) da placa é um dos métodos mais difundidos de estudo da placa aterosclerótica; nesse sentido, é importante criar uma padronização da pós-processamento de forma compreensível. O pós-processamento foi realizado no software Photoshop 23.1.1. A padronização da imagem foi alcançada com o ajuste de curvas do histograma de escalas de cinza definindo o ponto mais escuro do lúmen vascular (sangue) para zero e a adventícia distal para 190. A posterização e o remapeamento de cores foram realizados. Um método que apresenta o atual estado da arte da técnica de forma acessível e ilustrativa pode contribuir para disseminação da análise de GSM. Neste artigo, esse processo é demonstrado passo a passo.

Abstract Factors related to atherosclerotic plaques may indicate instability, such as ulcerations, intraplaque hemorrhages, lipid core, thin or irregular fibrous cap, and inflammation. The grayscale median (GSM) value is one of the most widespread methods of studying atherosclerotic plaques and it is therefore important to comprehensively standardize image post-processing. Post-processing was performed using Photoshop 23.1.1.202. Images were standardized by adjusting the grayscale histogram curves, setting the darkest point of the vascular lumen (blood) to zero and the distal adventitia to 190. Posterization and color mapping were performed. A methodology that presents the current state of the art in an accessible and illustrative way should contribute to the dissemination of GSM analysis. This article describes and illustrates the process step by step.
