Descriptive statistics summarized publication characteristics and citation counts at 2 and 5 years. Time to first citation was analyzed using Kaplan\u2013Meier estimators and Cox proportional hazards regression models, accounting for right-censored data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 3,968 publications were included. Most articles were published in open access journals (63.0%) and involved international collaboration (69.3%). Publications were predominantly in English (85.1%). Most records were original research articles (2,917; 73.5%), while 597 (15.0%) were review articles; article type information was unavailable for 454 records (11.4%). The median number of cumulative citations was 3 (IQR 1\u20137) at 2 years and 6 (IQR 3\u201314) at 5 years. Kaplan\u2013Meier analysis showed that approximately 50% of articles received their first citation within the first year, and most were cited within 4 years.
