目的评价并纵向比较中华心血管病杂志刊出科研论文研究设计和统计方法使用情况.方法对中华心血管病杂志第39卷1至12期中选定专栏文章的研究设计类型、统计方法使用情况进行整理,查找研究设计和统计方法中存在的问题,与第36卷评价中相应指标进行对比,探讨相应变化.结果 (1)两卷在研究设计类型分布上大体一致,第39卷研究中各种统计方法使用频率上升,生存分析和非参数方法应用比例增加,无统计分析文章比例下降.(2)第39卷中科研设计错误6篇(4％)、统计表述错误5篇(3％)、方法欠缺9篇(5％)均低于第36卷中各相应比例(10％、23％以及29％),差异均有统计意义.(3)第39卷中方差分析正确率有所提高,多组比较两两比较方法标注明确文章比例达到59％.计量资料正态性检验的研究比例第39卷高于第36卷,但方差齐性检验两卷相比差异无统计意义.由于对方差齐性的忽略,第39卷统计方法错误率为17％,与第36卷25％相比虽有所下降,但差异无统计意义(P=0.09).结论中华心血管病杂志第39卷刊出论文相比第36卷,在科研设计上更为合理,统计方法使用更为规范,在今后的研究分析中,对计量资料方差齐性的检验应当引起研究者的重视.

Objective To rc-cvaluate and compare the research design and the use of statistical methods in Chinese Journal of Cardiology.Method Summary the research design and statistical methods in all of theoriginal papers in Chinese Journal of Cardiology all over the year of 2011,and compared the result with the evaluation of 2008.Results (1) There is no difference in the distribution of the design of researches of between the two volumes.Compared with the early volume,the use of survival regression and non-parameter test are increased,while decreased in the proportion of articles with no statistical analysis.(2) The proportions of articles in the later volume are significant lower than the former,such as 6(4％)with flaws in designs,5(3％)with flaws in the expressions,9(5％)with the incomplete of analysis.(3) The rate of correction of variance analysis has been increased,so as the multi-group comparisons and the test of normality.The error rate of usage has been decreased form 17％ to 25％ without significance in statistics due to the ignorance of the test of homogeneity of variance.Conclusion Many improvements showed in Chinese Journal of Cardiology such as the regulation of the design and statistics.The homogeneity of variance should be paid more attention in the further application.
