Exploration of registration and the risk of bias in acupuncture randomised controlled trials: a systematic review protocol.

BACKGROUND: Randomised controlled trials (RCTs) are the predominant type in acupuncture clinical research, and the publications have increased rapidly in recent years, but there is a prevalence of the high risk of bias and poor methodological design in acupuncture RCTs. Clinical trial registration can improve the transparency and credibility of studies by disclosing key information in advance. However, the registration in acupuncture RCTs is not satisfactory, as there is widespread of the under-registration, inconsistency with published studies and insufficient disclosure of key methodological information. Whether registration can reduce the risk of bias in acupuncture RCTs and improve data transparency has not been fully explored. Therefore, we constructed this study to investigate the association between registration and risk of bias and data sharing level in acupuncture RCTs. METHODS: Seven databases including MEDLINE, EMBASE, CENTRAL, CBM, CNKI, Wanfang and VIP databases will be systematically searched between 1 January 2014 and 31 March 2024, for acupuncture RCTs. Two reviewers will independently extract data using a predefined standardised format and perform secondary validation. The characteristics and data sharing level of the included studies will be summarised. The risk of bias of included RCTs will be assessed by the revised Cochrane risk-of-bias tool for randomised trials. The risk of bias and registration in acupuncture RCTs will be analysed by logistic or quantile regression analyses (depending on the number of minimum events). The data sharing level and registration will be analysed by quantile regression analyses. ETHICS AND DISSEMINATION: As the systematic review aims to consolidate info from published sources, ethical approval is not necessary for this study. The study's findings will be submitted to a peer-reviewed academic journal and disseminated via conference presentations. This protocol has been registered in Open Science Framework Registries.

Reporting and influencing factors of patient-reported outcomes in acupuncture randomised controlled trials: a cross-sectional study protocol.

INTRODUCTION: Patient-reported outcomes (PROs) are health reports that come directly from the patients themselves and represented the experience and insights of the patient's perspective on the impact of the intervention. PROs were increasingly emphasised in acupuncture randomised controlled trials (RCTs). However, the reporting quality of PROs in acupuncture RCTs has not been investigated to date. Therefore, we constructed this study to reveal the basic characteristics and reporting quality of PROs in acupuncture RCTs, and explore the relationship between concealment, blinding and RROs. We hope our findings can provide guidance for the reporting standards and future development of PROs in acupuncture RCTs in reverse. METHODS AND ANALYSIS: RCTs using acupuncture treatment as the intervention and PROs as primary outcomes or secondary outcomes will be systematically searched through seven databases MEDLINE, EMBASE, CENTRAL, CBM, CNKI, Wanfang and VIP between 1 January 2012 and 15 October 2022. The basic characteristics, concealment, blinding design and the characteristics of PROs in included RCTs will be summarised. The reporting quality of PROs will be assessed based on the CONSORT PRO extension. Logistic analysis will be performed to identify the association between concealment, blinding and RROs. ETHICS AND DISSEMINATION: Ethical approval is not required for this study. This protocol has been registered in Open Science Framework (OSF) Registries. The findings of this study will be submitted to a peer-reviewed academic journal.

Reporting and data-sharing level of acupuncture randomised controlled trials: a cross-sectional study protocol.

INTRODUCTION: Randomised controlled trials (RCTs) play an important role in evidence-based medicine. However, an article with low reporting quality may mislead both experts and the general public into an erroneous decision. Data sharing can contribute to the truthfulness and transparency of trials. Acupuncture RCTs have been increasing rapidly these years, but the reporting quality and data-sharing level of acupuncture RCTs are not clear. Thus, this study will provide the current status of the reporting quality and data-sharing level of acupuncture RCTs. METHODS AND ANALYSIS: A cross-sectional study will be conducted. The seven databases including MEDLINE, EMBASE, CENTRAL, CBM, CNKI, Wanfang Database and VIP will be searched between 1 January 2012 and 15 October 2022 to identify acupuncture RCTs. The basic characteristics of included trials will be summarised. The reporting quality for included RCTs will be assessed by the Consolidated Standards for Reporting Trials 2010 statement and the Standards for Reporting Interventions in Controlled Trials of Acupuncture. The data-sharing level will be assessed by open science practices. ETHICS AND DISSEMINATION: Ethical approval is not required for this study. This protocol has been registered in Open Science Framework Registries. The findings of this study will be submitted to a peer-reviewed academic journal.
