The Thoracic Surgery Social Media Network (TSSMN) is a collaborative effort of leading journals in cardiothoracic surgery to highlight publications via social media. This study aims to evaluate the 1-year results of a prospective randomized social media trial to determine the effect of tweeting on subsequent citations and nontraditional bibliometrics.
A total of 112 representative original articles were randomized 1:1 to be tweeted via TSSMN or a control (non-tweeted) group. Measured endpoints included citations at 1 year compared with baseline, as well as article-level metrics (Altmetric score) and Twitter analytics. Independent predictors of citations were identified through univariable and multivariable regression analyses.
When compared with control articles, tweeted articles achieved significantly greater increase in Altmetric scores (Tweeted 9.4 ± 5.8 vs Non-tweeted 1.0 ± 1.8, P < .001), Altmetric score percentiles relative to articles of similar age from each respective journal (Tweeted 76.0 ± 9.1 percentile vs Non-tweeted 13.8 ± 22.7 percentile, P < .001), with greater change in citations at 1 year (Tweeted +3.1 ± 2.4 vs Non-Tweeted +0.7 ± 1.3, P < .001). Multivariable analysis showed that independent predictors of citations were randomization to tweeting (odds ratio [OR] 9.50; 95% confidence interval [CI] 3.30-27.35, P < .001), Altmetric score (OR 1.32; 95% CI 1.15-1.50, P < .001), open-access status (OR 1.56; 95% CI 1.21-1.78, P < .001), and exposure to a larger number of Twitter followers as quantified by impressions (OR 1.30, 95% CI 1.10-1.49, P < .001).
One-year follow-up of this TSSMN prospective randomized trial importantly demonstrates that tweeting results in significantly more article citations over time, highlighting the durable scholarly impact of social media activity.
胸外科社交媒体网络（TSSMN）是心胸外科领域领先期刊的合作努力，旨在通过社交媒体突出发表的文章。本研究旨在评估一项前瞻性随机社交媒体试验的 1 年结果，以确定发推文对后续引文和非传统文献计量学的影响。
共有 112 篇具有代表性的原始文章被随机分为 1:1 组，通过 TSSMN 或对照组（未发推文）进行推文。测量终点包括与基线相比 1 年内的引文，以及文章级别的指标（Altmetric 分数）和 Twitter 分析。通过单变量和多变量回归分析确定引文的独立预测因素。
与对照组文章相比，发推文的文章的 Altmetric 分数显著增加（推文 9.4 ± 5.8 与非推文 1.0 ± 1.8，P <.001），相对于每个期刊中年龄相似的文章的 Altmetric 分数百分比（推文 76.0 ± 9.1 百分比与非推文 13.8 ± 22.7 百分比，P <.001），并且在 1 年内的引文变化更大（推文 +3.1 ± 2.4 与非推文 +0.7 ± 1.3，P <.001）。多变量分析表明，引文的独立预测因素是随机分组进行推文（比值比[OR] 9.50；95%置信区间[CI] 3.30-27.35，P <.001），Altmetric 分数（OR 1.32；95% CI 1.15-1.50，P <.001），开放获取状态（OR 1.56；95% CI 1.21-1.78，P <.001）以及通过印象量化的更多 Twitter 关注者的暴露（OR 1.30，95% CI 1.10-1.49，P <.001）。
本 TSSMN 前瞻性随机试验的 1 年随访结果重要地表明，随着时间的推移，推文会导致文章引文显著增加，突出了社交媒体活动的持久学术影响力。
