以心律学科为例,比较Heart Rhythm和《中华心律失常学杂志》刊载的临床论著在证据分类和分级以及统计方法应用方面的差异。检索2012年全年Heart Rhythm和《中华心律失常学杂志》刊载的临床论著,发现中外期刊论文的研究类型有显著差异,表现为国内研究类型较为单一。证据等级国内论文略低于国外,特别是随机对照试验过少,但两者差异无统计学意义。统计方法的应用上,国内论文在非参数检验、回归分析及生存分析方面明显低于国外论文。
In the case of heart rhythm, we compared the differences in evidence classification and grading as well as the application of statistical methods in the clinical articles published by Heart Rhythm and Chinese Journal of Cardiac Arrhythmias. Retrieved 2012 Annual Heart Rhythm and published in the “Chinese Journal of Arrhythmia,” the clinical research found that Chinese and foreign journal articles are significantly different types of research, the performance of the type of domestic research is more single. Evidence level Domestic papers slightly lower than abroad, especially in randomized controlled trials too little, but the difference was not statistically significant. The application of statistical methods, domestic papers in non-parametric test, regression analysis and survival analysis was significantly lower than the foreign papers.
