The continuum of evidence-based medicine (EBM) depends solely on clinicians' commitment to keep current with the latest clinical information. Exploration on clinicians' understanding of biostatistical results in the medical literature is sparse to date. This study aimed to evaluate clinicians' perceived understanding of biostatistical results in the medical literature and the factors influencing them. A cross-sectional study was conducted among 201 clinicians at the Seberang Jaya Hospital, a cluster-lead research hospital in Northern Malaysia. A self-administered questionnaire that consisted of items on sociodemographics, validated items on clinicians' confidence level in interpreting statistical concepts, perceived understanding of biostatistics, and familiarity with different statistical methods were used. Descriptive, univariate, and multivariate analyses were conducted. Perceived understanding of biostatistical results among clinicians in our sample was nearly 75%. In the final regression model, perceived understanding was significantly higher among clinicians who were able to interpret -values with complete confidence (AOR = 3.0, 95% CI 1.1-8.1), clinicians who regularly encounter measures of central tendencies (AOR = 2.3, 95% CI 1.1-5.2), and clinicians who regularly encounter inferential statistics (AOR = 2.2, 95% CI 1.1-4.5) while appraising the medical literature. High perceived understanding was significantly associated with clinicians' confidence in interpreting statistical concepts and familiarity with different statistical methods. Our findings form a platform to understand clinicians' ability to appraise rigorous biostatistical results in the medical literature for the retrieval of evidence-based data to be used in routine clinical practice.
循证医学（EBM）的连续性完全取决于临床医生是否致力于及时掌握最新的临床信息。迄今为止，对临床医生如何理解医学文献中的生物统计学结果的研究甚少。本研究旨在评估临床医生对医学文献中生物统计学结果的理解程度及其影响因素。
在马来西亚北部的一个集群领导研究医院——Seberang Jaya 医院，对 201 名临床医生进行了横断面研究。使用的问卷包括社会人口统计学项目、验证过的临床医生解释统计概念的信心水平项目、对生物统计学的理解程度项目和对不同统计方法的熟悉程度项目。进行了描述性、单变量和多变量分析。
我们样本中临床医生对生物统计学结果的理解程度接近 75%。在最终的回归模型中，能够完全自信地解释 P 值的临床医生（AOR = 3.0，95%CI 1.1-8.1）、经常遇到集中趋势度量的临床医生（AOR = 2.3，95%CI 1.1-5.2）和经常遇到推论统计的临床医生（AOR = 2.2，95%CI 1.1-4.5）对医学文献进行评估时，其对生物统计学结果的理解程度显著更高。
高理解程度与临床医生解释统计概念的信心和对不同统计方法的熟悉程度显著相关。我们的研究结果为理解临床医生在医学文献中评估严格的生物统计学结果以检索用于常规临床实践的循证数据的能力提供了一个平台。
