医生依靠医学文献来了解最新的临床信息。人们对居民理解统计方法的能力或如何恰当地解释研究结果知之甚少。目的了解居民对生物统计学的理解情况及对研究结果的解释情况。设计、设置和参与者：内科住院医师的多项目横断面调查。生物统计学/研究设计多项选择题知识测试答对题目的百分比。结果11个住院医师项目367名住院医师中，有277人（75.5%）完成了调查。统计知识和结果解释的总体平均正确率为41.4%(95%置信区间[Cl]， 39.7% ~ 43.3%)，而接受过研究培训的研究员和普通医学教师的总体平均正确率为71.5%（95%置信区间[Cl]， 57.5% ~ 85.5%）
Context Physicians depend on the medical literature to keep current with clinical information. Little is known about residents' ability to understand statistical methods or how to appropriately interpret research outcomes.Objective To evaluate residents' understanding of biostatistics and interpretation of research results.Design, Setting, and Participants Multiprogram cross-sectional survey of internal medicine residents.Main Outcome Measure Percentage of questions correct on a biostatistics/study design multiple-choice knowledge test.Results The survey was completed by 277 of 367 residents (75.5%) in 11 residency programs. The overall mean percentage correct on statistical knowledge and interpretation of results was 41.4% (95% confidence interval [ Cl], 39.7%-43.3%) vs 71.5% ( 95% Cl, 57.5%-85.5%) for fellows and general medicine faculty with research training ( P
