Randomized trials are often presented at medical conferences and published simultaneously or later. Predictors of simultaneous publication and its consequences are undetermined. Our aim was to characterize the practice of simultaneous publication, identify its predictors, and evaluate its impact.
In this cross-sectional study, we included randomized trials presented at late-breaking science sessions of major cardiovascular conferences from 2015 to 2021. The association of trial characteristics with the timing of publication was analyzed. The impact of simultaneous vs nonsimultaneous publication was investigated on the number of 1-year citations and 1-month mentions, and the total citations and mentions at the longest observation follow-up.
Of 478 trials included in the analysis, 48.7% were published simultaneously. Simultaneous publications were more likely to be presented in the main conference room (OR, 6.09; 95%CI, 1.34-36.92; P=.029) and were characterized by a shorter review time (OR, 0.95; 95%CI, 0.91-0.96; P<.001). Simultaneous publications were associated with higher 1-year citations (R, 43.81; 95%CI, 23.89-63.73; P<.001), 1-month mentions (R, 132.32; 95%CI, 85.42-179.22; P<.001) and total citations (R, 222.89; 95%CI, 127.98-317.80; P<.001).
Randomized trials presented in the main conference room and with shorter review time were more likely to be published simultaneously. Simultaneous publications were associated with more citations and mentions than nonsimultaneous publications.
随机试验经常在医学会议上展示，并同时或之后发表。同步发表的预测因素及其后果尚未确定。我们的目的是描述同步发表的情况，确定其预测因素，并评估其影响。
在这项横断面研究中，我们纳入了2015年至2021年在主要心血管会议的最新科学会议上展示的随机试验。分析了试验特征与发表时间的关联。研究了同步发表与非同步发表对1年引用次数和1个月提及次数，以及最长观察随访期的总引用次数和提及次数的影响。
在纳入分析的478项试验中，48.7%是同步发表的。同步发表的试验更有可能在主会议室展示（比值比，6.09；95%置信区间，1.34 - 36.92；P = 0.029），其特点是审稿时间较短（比值比，0.95；95%置信区间，0.91 - 0.96；P < 0.001）。同步发表与更高的1年引用次数（R，43.81；95%置信区间，23.89 - 63.73；P < 0.001）、1个月提及次数（R，132.32；95%置信区间，85.42 - 179.22；P < 0.001）和总引用次数（R，222.89；95%置信区间，127.98 - 317.80；P < 0.001）相关。
在主会议室展示且审稿时间较短的随机试验更有可能同步发表。与非同步发表相比，同步发表的引用次数和提及次数更多。
