【摘要】 目的:以中华医学会肿瘤学期刊为例,评价中文肿瘤学干预类Meta分析摘要报告质量,并分析影响摘要报告质量的因素。方法:利用中国知网(CNKI)检索中华医学会肿瘤学期刊发表的干预类Meta分析论文,并收集论文的特征信息,将PRISMA-A声明的12个条目评价纳入论文的摘要报告质量,通过单因素和多因素分析探究影响摘要报告质量的关键因素。结果:共纳入147篇肿瘤干预类Meta分析论文,PRISMA-A的摘要评价总分平均为8.32±1.06分,有7个条目的报告率在85.00%以上,报告率最低的3个条目是关于基金(0.00%)、注册(0.00%)和偏倚风险评估方法(12.24%)的说明。摘要报告的高低质量组在来源期刊及摘要字数方面有显著差异(P<0.01)。多因素分析结果表明,摘要字数为影响报告质量的独立因素(P=0.002)。结论:中华医学会肿瘤学期刊发表的中文肿瘤干预类Meta分析摘要中,大部分信息条目的报告率较高,但对基金、注册和偏倚风险评估方法的报告率有待提高。适当增加摘要字数是改善摘要报告质量的一项有效措施。更多还原

【Abstract】 Objective To assess the reporting quality of abstracts in meta-analysis papers on intervention published in Chinese medical journals and to analyze its influencing factors with oncology journals of Chinese Medical Association as an example. Methods The papers on intervention with meta-analysis published in oncology journal of Chinese Medical Association were retrieved from CNKI and their characteristic information was recorded. The reporting quality of abstracts in the papers on intervention included in this study was assessed according to the 12 items included in the statement of preferred reporting items for systematic reviews and meta-analyses for abstracts( PRISMA-A). The key factors influencing the reporting quality of abstracts in papers on intervention were analyzed by univariate analysis and multivariate analysis respectively.Results A total of 147 papers on intervention with meta-analysis were included in this study. The total score of abstracts was 8.32 ± 1.06 according to the statement of PRISMA-A. The reporting rate of 7 items in statement of PRISMA-A was > 85.00% and that of funding,registration and bias risk assessment methods was the lowest,which was0.00%,0.00% and 12.24% respectively. Significant differences were detected in different journals and in words of abstract between the high reporting quality group and low reporting quality group( P<0.01). Multivariate analysis showed that the words of abstract were an independent factor influencing the reporting quality of abstracts in papers on intervention( P = 0.002). Conclusion The reporting rate of most information items in abstracts on intervention with meta-analysis published in oncology journals of Chinese Medical Association is relatively high,but that of funding,registration and bias risk assessment methods needs to be increased. It is an effective measure to improve the reporting quality of abstracts by appropriately increasing the words of abstract.更多还原
