目的 分析2017-2022年国内外中医药疗效评价队列研究的现状与趋势,为该领域的研究提供参考.方法 检索 PubMed、Web of Science、Embase、Scopus、Cochrane Library及中国知网(CNKI)2017年 1月1日—2022年12月31日收录的中医药疗效评价队列研究文献.使用Bibliometrix对相关文献从年发文量、发文期刊、高被引文献及关键词进行定量和可视化分析.结果 共纳入328篇文献,涉及141本期刊.2017-2022年中医药疗效评价队列研究相关的发文量整体呈逐年上升趋势,纳入文献以回顾性队列研究为主(282篇,85.98%),依托数据库开展的队列研究共151篇(46.04%),且逐年增长.研究对象以恶性肿瘤(77篇,23.48%)及心脑血管疾病患者(64篇,19.51%)为主,排名前3的高被引文献均旨在探讨中医药干预恶性肿瘤患者的生存结局及生活质量.中英文文献分别包含14及25个高频关键词,各自形成以研究方法、统计分析及疾病类型为主的3个聚类.结论 中医药疗效评价队列研究主要为回顾性队列研究,且聚焦于恶性肿瘤及心脑血管系统疾病患者,利用观察性数据库开展中医药疗效评价队列研究可能是未来的发展趋势.
Objective To explore the research status and trends of cohort studies on traditional Chinese medi-cine(TCM)efficacy evaluation from 2017 to 2022 and provide ideas and references for research in this field.Methods Six databases including Pubmed,Web of Science,Embase,Scopus,Cochrane Library and CNKI were searched from January 1st,2017 to December 31st,2022.The total number of annual publications,journals,highly cited litera-tures,and keywords were quantitatively and visually analyzed by Bibliometrix.Results A total of 328 articles were included,which were published in 141 journals.The number of articles published in this field showed an overall upward trend,and retrospective cohort studies(282 papers,85.98%)accounted for the largest proportion.A total of 151 cohort studies(46.04%)were conducted based on the database and showed an overall upward trend.The sub-jects were mainly patients with tumors(77 papers,23.48%),and cardiovascular and cerebrovascular diseases(64 papers,19.51%).The top 3 highly cited literatures mainly explore the association between TCM and survival out-come and quality of life in patients with malignant tumors.Fourteen and twenty-five high-frequency keywords were included in Chinese and English literature respectively,which formed 3 clusters such as research methods,statis-tical analysis and diseases.Conclusion It was the current status to focus on retrospective cohort studies and focus on patients with tumors or cardiovascular and cerebrovascular diseases.Using observational database to conduct cohort studies of TCM efficacy evaluation could be the future research direction.
