RESUMO
Objective:To evaluate the methodological quality and evidence quality of outcome of the systematic reviews/meta analyses on traditional exercise for the improvement of cardiopulmonary function.Methods:By searching for PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, VIP and CBM databases in Chinese or English, the Systematic Reviews/meta analysis of traditional exercises for improving cardiopulmonary function was conducted. The retrieval time was March 8th, 2020. The AMSTAR 2 scale was used to evaluate the methodological quality of the systematic review/meta-analysis that met the inclusion criteria. Since the included studies cannot reflect the overall effect of traditional exercises on improving cardiopulmonary function, and the methodological quality of systematic reviews was generally low, a secondary analysis of the RCT studies included in the systematic reviews was conducted. The methodological quality evaluation of the original RCT study adopted the Cochrane Reviewers’ Handbook Version 5.0.0 bias risk assessment method (Risk of Bias, ROB), and applied the Revman 5.3 software to merge the original RCT data. The GRADE system was used for evidence evaluation.Results:A total of 32 systematic reviews/meta analysis were included, and the AMSTAR2 scale indicated that only one of the 32 systematic reviews/meta included was of high-quality, 1 was of low-quality, and the others were of extremely low quality. A total of 57 RCTs were included in the 32 systematic reviews for bias risk assessment and data consolidation. GRADE evidence quality evaluation showed that 14 evidences were of medium quality, 26 evidences were of low quality, and 5 evidences were of extremely low quality.Conclusions:Traditional exercises can improve cardiopulmonary function, but with low evidence quality. Thus, clinicians should make clinical decisions based on conditions.
RESUMO
Objective We aim to objectively evaluate the influence of six-character formula on patients with stable chronic obstructive pulmonary disease (COPD).Methods The randomized controlled trials (RCTs) which investigated the influence of six-character formula on patients with COPD were electronically searched in the databases such as China National Knowledge Infrastructure (CNKI),Chinese Science Technology Periodical Databases (VIP),Wanfang Data,PubMed,The Cochrane Library (Issue 6,2014) and ELSEVIER.According to the inclusion and exclusion criteria,the references was screened,the data were extracted and the methodological quality of the included articles was assessed.Then,Meta-analy-sis was performed using RevMan 5.3 software.Results A total of 10 studies involved,578 patients were included.The result of Meta-analysis showed that compared with the control group,six-character formula significantly improved six-minute walk distance,forced expiratory volume in a second (FEV1) and FEV1 predicted value,reduced the score of activity limitation and the impact of the disease in St George's respiratory questionnaire (SGRQ).the value of MD and 95％CI were 22.62 (10.49-34.75),0.10 (0.01-0.18),3.08 (0.18-5.97),8.69 (4.09-13.83),7.60 (2.34-12.85).However,there was no statistical difference in the score of symptom.Conclusions Six-character formula plays a significant role in the treatment of stable COPD.However,more studies in large scale and high quality are needed to verify the result.
