Altmetric Attention Score (AAS) is an alternative metric for estimating the impact of academic publications. We studied the association of using podcasting to highlight publications about gynecological cancer with AAS and citation scores.
Articles that were featured in the (IJGC) podcast series January 2019 to September 2022 were matched 1:1 to control articles by the journal in which the article was published, study topic and design, single/multicenter data, and year of publication. Podcast articles were compared with matched-controls by citation metrics and altmetric scores.
A total of 99 podcasted articles published in 16 journals were matched. Median AAS was significantly higher in the podcast group than the matched-control group (22 (14-42) vs 5 (1-17), p<0.001). In a multivariable regression analysis, podcasting was the only factor associated with a high AAS (adjusted odds ratio (aOR) 8.6, 95% CI 3.8 to 19.7). In the podcast group, the median number of citations per year was higher than matched-control studies (5.5 (3.0-12.7) vs 4.5 (2.0-9.5), p=0.047). The only article characteristics that were independently associated with ≥12 citations per year were if the publication described a randomized controlled trial (aOR 4.7, 95% CI 1.6 to 13.6) or featured cervical carcinoma as the subject focus (aOR 2.9, 95% CI 1.3 to 6.5). Compared with all articles published in IJGC during the study period, articles that were featured in a podcast had higher median citations per year (5 (2-10) vs 1 (0-2.5), p<0.001).
When compared with matched-controls, podcasting an article is associated with a higher AAS but is not associated with generating a high (≥12) number of citations per year. When compared with all articles published in the same journal during the same study period, articles that were featured in a podcast had higher median citations per year.
Altmetric Attention Score（AAS）是一种用于估计学术出版物影响力的替代指标。我们研究了通过播客突出妇科癌症相关出版物来使用播客与 AAS 和引文分数的关联。
将 2019 年 1 月至 2022 年 9 月发表在《国际妇科癌症杂志》（IJGC）播客系列中的文章与发表在该期刊中的对照文章进行 1:1 匹配，对照文章根据文章主题和设计、单中心/多中心数据和出版年份进行匹配。通过引文计量和替代计量分数比较播客文章和对照文章。
共匹配了 16 种期刊上发表的 99 篇播客文章。播客组的 AAS 中位数明显高于对照组（22（14-42）比 5（1-17），p<0.001）。在多变量回归分析中，播客是唯一与高 AAS 相关的因素（调整后的优势比（aOR）8.6，95%CI 3.8 至 19.7）。在播客组中，每年的平均引文数高于对照组研究（5.5（3.0-12.7）比 4.5（2.0-9.5），p=0.047）。唯一与每年≥12 次引用独立相关的出版物特征是如果该出版物描述了一项随机对照试验（aOR 4.7，95%CI 1.6 至 13.6）或以宫颈癌为主题（aOR 2.9，95%CI 1.3 至 6.5）。与研究期间 IJGC 发表的所有文章相比，播客中的文章每年的平均引用中位数更高（5（2-10）比 1（0-2.5），p<0.001）。
与对照组相比，播客一篇文章与 AAS 更高相关，但与每年产生高（≥12）引用次数无关。与同一研究期间在同一期刊上发表的所有文章相比，播客中的文章每年的平均引用中位数更高。
