Abstract: OBJECTIVE: Our objective was to characterize the most frequently 
cited articles published in obstetrics and gynecology journals during the last 50 
years.
STUDY DESIGN: We utilized the 2008 edition of Journal Citation Reports and 
Social Sciences Citation Index database to determine the most frequently cited 
articles published after 1956. Articles were evaluated for several 
characteristics, and an unadjusted categorical analysis was performed to 
compare pre- and post-1980 articles.
RESULTS: The 100 most frequently cited articles were published in 11 journals 
between 1957 and 2004. Most articles were published by US-based authors. 
Forty-four articles were related to obstetrics and 56 were related to 
gynecology. The most common study design was observational. There were 
only 7 randomized controlled trials, and randomized controlled trials were not 
more common after 1980 (6.3% vs 8.1%; P = .71).
CONCLUSION: Most "citation classics" in obstetrics and gynecology are 
observational studies published in high-impact journals by US-based authors 
after 1980.
