Research productivity impacts an individual's academic credentials and serves to advance the field of neurosurgery at large. Poster presentations allow researchers to share preliminary results with respected colleagues; however, more critical is the ability to publish peer-reviewed articles. Key factors that lead posters to journal publication are not well understood and difficult to quantify. This study investigates the association between bibliometrics of authors who presented posters at the North American Skull Base Society (NASBS) meeting and odds of journal publication. Posters from the 2016 to 2018 NASBS archive were reviewed. Hirsch-index (h-index) of first (FH) and senior (SH) authors, research type, research topic, and number of poster authors (nAuthPost) were collected. For posters published as journal articles, number of days from poster presentation to publication (nDays), number of authors in published articles (nAuthArt), and journal impact factor (JIF) were recorded. One-hundred sixty-nine of 481 posters (35.1%) were published as articles. Median FH and SH for published versus unpublished posters were 7 versus 5 ( = 0.01) and 29 versus 19 ( < 0.001), respectively. When adjusted with multivariate regression, only SH ( < 0.001) and nAuthPost ( = 0.001) were significantly associated with odds of publication. Median (interquartile range [IQR]) nDays was 361 (394). Increased authors from poster to article ( = 0.017) and lower FH ( = 0.08) were correlated with increased time to publication. Median (IQR) JIF for all publications was 1.723 (1.068). Bibliometrics such as h-index and number of authors from posters can help objectively characterize and predict future success in research productivity.
研究产出会影响个人的学术资历，并有助于推动整个神经外科领域的发展。海报展示使研究人员能够与受尊敬的同行分享初步研究结果；然而，更关键的是发表经过同行评审文章的能力。导致海报最终发表为期刊文章的关键因素尚未得到充分理解，也难以量化。本研究调查了在北美颅底学会（NASBS）会议上展示海报的作者的文献计量学指标与期刊发表几率之间的关联。
对2016年至2018年NASBS存档的海报进行了回顾。收集了第一作者（FH）和资深作者（SH）的Hirsch指数（h指数）、研究类型、研究主题以及海报作者数量（nAuthPost）。对于发表为期刊文章的海报，记录了从海报展示到发表的天数（nDays）、发表文章的作者数量（nAuthArt）以及期刊影响因子（JIF）。
481张海报中有169张（35.1%）发表为文章。已发表与未发表海报的FH中位数分别为7和5（ = 0.01），SH中位数分别为29和19（ < 0.001）。在进行多变量回归调整后，只有SH（ < 0.001）和nAuthPost（ = 0.001）与发表几率显著相关。nDays的中位数（四分位间距[IQR]）为361（394）。从海报到文章作者数量增加（ = 0.017）以及FH较低（ = 0.08）与发表时间延长相关。所有出版物的JIF中位数（IQR）为1.723（1.068）。
诸如h指数和海报作者数量等文献计量学指标有助于客观地描述和预测未来研究产出方面的成功。
