INTRODUCTION
Research projects use statistical resources to express in numerical or graphic terms different magnitudes like frequencies, differences or associations.
OBJECTIVES
The purpose of this paper is to describe the statistics tools utilization, with special emphasis in the use of conventional statistical tests and confidence intervals, to communicate results in a renowned public health peer reviewed journal in Colombia.
METHODS
We included the 84 articles published in the journal between 2013 and 2014.
RESULTS
The most used resource is frequency analysis (89.3%), followed by p values (65.5%) and confidence intervals (53.6%); 48.9% of the papers used confidence intervals together with p values; 29.8% use neither of them; 16.7% of the articles only used p values and 4.8% only confidence intervals.
CONCLUSIONS
Descriptive statistics is a tool widely used in research results presentation; the critics and caveats suggesting to avoid the exclusive use of the statistical signification test in the results presentation are not followed in the analysis and presentation of the research results.
引言
研究项目使用统计资源以数字或图表形式来表达不同的量值，如频率、差异或关联。
目的
本文旨在描述统计学工具的使用情况，特别强调传统统计检验和置信区间的使用，以便在哥伦比亚一本著名的公共卫生同行评审期刊上交流研究结果。
方法
我们纳入了该期刊在2013年至2014年期间发表的84篇文章。
结果
最常用的资源是频率分析（89.3%），其次是p值（65.5%）和置信区间（53.6%）；48.9%的论文同时使用了置信区间和p值；29.8%的论文两者都未使用；16.7%的文章仅使用了p值，4.8%的文章仅使用了置信区间。
结论
描述性统计是研究结果呈现中广泛使用的工具；在研究结果的分析和呈现中，并未遵循那些建议避免在结果呈现中仅使用统计显著性检验的批评意见和注意事项。
