We sought to determine (1) whether United States Medical Licensing Examination (USMLE) scores predict academic productivity in neuroradiology fellows as measured by publications and citations, and (2) what factors predict such productivity.
We reviewed the USMLE scores, gender, medical school location attended, publication record before and during fellowship, fellowship evaluation ratings and subsequent practice site (private vs academic) of neuroradiology fellows from 2004 to 2014 to determine relationships with publications and citations after fellowship. Spearman's correlation and Poisson regression analyses were performed to assess the association between these factors and quantity of publications and citations per year after fellowship.
USMLE scores and fellowship evaluation scores correlated inversely with radiology publications and citations. There were strong correlations between publication records before or during fellowship and after fellowship. Fellows from international medical schools, with PhD degrees, and those fellows proceeding to academic practice had more publications before or during and after neuroradiology fellowship.
The best predictors of whether a graduating neuroradiology fellow will publish and have high citation rates is prior publication record, a PhD degree, and staying in academics. USMLE scores and evaluations during the fellowship were inversely correlated with publication measures of academic productivity.
我们试图确定（1）美国医师执照考试（USMLE）成绩是否能预测神经放射学研究员的学术产出，以出版物数量和引用次数来衡量；以及（2）哪些因素能预测这种产出。
我们回顾了2004年至2014年神经放射学研究员的USMLE成绩、性别、就读医学院校所在地、研究员培训前及培训期间的出版记录、研究员培训评估评分以及随后的执业地点（私立与学术机构），以确定与研究员培训后的出版物和引用次数之间的关系。进行了Spearman相关性分析和Poisson回归分析，以评估这些因素与研究员培训后每年出版物数量和引用次数之间的关联。
USMLE成绩和研究员培训评估分数与放射学出版物及引用次数呈负相关。研究员培训前或培训期间与培训后的出版记录之间存在强相关性。毕业于国际医学院校、拥有博士学位以及从事学术实践的研究员在神经放射学研究员培训前、培训期间及培训后发表的文章更多。
即将毕业的神经放射学研究员是否会发表文章并获得高引用率的最佳预测因素是既往出版记录、博士学位以及留在学术界。研究员培训期间的USMLE成绩和评估与学术产出的出版指标呈负相关。
