ABSTRACT Purpose Our purpose was to measure the research output and impact of the Canadian Network for Observational Drug Effect Studies (CNODES). Methods We used OpenAlex to collect metadata on citation counts for all 115 CNODES articles published between January 2011 and March 2022. We obtained the altmetric scores from Altmetric.com . We examined mean citation counts and altmetric scores overall and by publication venue, study type, and author characteristics. We used general linear and mixed effects modeling to examine the association of citation counts/altmetric scores with the following characteristics: author's gender, trainee status and institution, study design, journal venue, article type, and jurisdiction(s) of data. Results In total, 232 authors co‐authored at least one publication. While about half of authors were women, men accounted for two‐thirds of authorships. Trainees accounted for 28% of first authorships. The median citation count was 19.0 (interquartile range: 9.0–52.0), and the median altmetrics score was 4.0 (interquartile range: 1.0–22.0). Compared with original, observational research, methodologic research was associated with a lower altmetric score (adjusted difference: −57.4, 95% CI: −87.7; −27.1) but not citation counts (adjusted difference: 40.5, 95% CI: −26.2; 107.1). Publication in a “top 10” medical journal was associated with higher citation counts (adjusted difference: 89.8, 95% CI: 42.1, 137.5) and altmetric scores (adjusted difference: 168.3, 95% CI: 91.1, 245.5) scores. Conclusions The patterns identified using bibliometrics and altmetrics demonstrated CNODES's author and institutional networks and their publications' mobilization and use by the academic community and broader publics.
