【摘要】：目的调查医学期刊论文中各种统计图的使用比例及常见错误的出现比例。方法采用两阶段完全随机抽样,对医学期刊文献中各种统计图的使用比例及其常见应用错误的比例进行统计分析。结果 1998-2012年收录文献中统计图的使用率为7.4%;统计图使用错误的比例为14.3%,图序编制不规范、标题缺失、标题位置不正确、横纵坐标设置不规范及图例应用不规范的比例分别为2.2%,0.5%,2.0%,9.4%,3.8%。不同文献发表年份中统计图使用错误比例、直条图使用错误比例、图序使用不规范比例、横纵标目使用不规范比例差异均有统计学意义(P0.05);不同作者学历水平和不同课题资助类型间统计图的使用比例差异有统计学意义(P0.05)。结论医学文献中统计图的使用比例不高,但其使用错误的比例相对较高;近年来由于统计教学改革统计图的使用及错误情况得到改善,但是仍然受到作者学历及基金资助等因素的限制。
[Abstract]:Objective to investigate the use of various statistical charts and the occurrence rate of common errors in medical journal papers. Methods Two-stage complete random sampling was used. The use rate of various statistical charts and the proportion of common application errors in the literature of medical journals were analyzed statistically. Results the utilization rate of statistical charts in the literature collected from 1998 to 2012 was 7.4%. The proportion of error in the use of statistical charts was 14. 3%. The proportion of irregular drawing order, missing title, incorrect position of title, nonstandard setting of vertical coordinate and irregular application of legend were 2.2% respectively. The proportion of errors in the use of statistical charts, the proportion of errors in the use of straight bar charts, and the proportion of irregular use of charts in the years of publication of different documents. There were significant differences in the proportion of non-standard use of horizontal and vertical standard items (P 0.05). There were significant differences in the proportion of the use of statistical maps among different authors' educational level and different types of financial assistance. Conclusion the proportion of statistical charts used in medical literature is not high. However, the proportion of its use errors is relatively high; In recent years, the use of statistical charts and errors in statistical teaching reform have been improved, but they are still restricted by factors such as the author's educational background and fund support.

【正文快照】： 统计图用点的位置、线段的升降、直条的长短或面积的大小等形式表达数据信息[1]。一幅设计合理的统计图,有利于读者理解,寻找规律,引出结论,有时其作用远胜于文字[2]。统计图也是医学论文的重要表达形式,可以反映各类医学现象的演变过程及变化规律,越来越受到国内外学者的重视
