This article presents a review of the statistical analyses used by authors and published in The Journal of Foot & Ankle Surgery from January 2004 to December 2008. Of the 215 articles reviewed, descriptive statistics were used in 84% and comparative statistics in 68%. The most commonly used comparative statistical tests were Student t test (30%), analysis of variance (14%), the Mann Whitney U test (Wilcoxon rank sum) test (13%), chi-squared analyses (11%), and Fisher's exact test (10%). The aim of this investigation was to review the prevalences of various statistical methods used by foot and ankle surgeons, as reported in The Journal of Foot & Ankle Surgery, and to serve as a primer of the most common methods used in the analysis of surgical data and the development of a scientific basis for the practice of foot and ankle surgery.
本文对2004年1月至2008年12月期间作者发表在《足踝外科杂志》上的统计分析方法进行了综述。在215篇被综述的文章中，84%使用了描述性统计，68%使用了比较性统计。最常用的比较性统计检验是学生t检验（30%）、方差分析（14%）、曼-惠特尼U检验（威尔科克森秩和检验）（13%）、卡方分析（11%）和费舍尔精确检验（10%）。本研究的目的是回顾《足踝外科杂志》报道的足踝外科医生使用的各种统计方法的流行情况，并作为手术数据分析中最常用方法的入门介绍，为足踝外科手术实践建立科学基础。
