The numbers of publications of different levels of evidence by journal in 2000, 2005, and 2010 are shown. Data are plotted as number rather than proportion because of differences in publication volumes between subspecialties. Abbreviations are: LOE = level of evidence; JOT = Journal of Orthopaedic Trauma; FAI = Foot and Ankle International; JHS = Journal of Hand Surgery; Arth = Journal of Arthroplasty; JSES = Journal of Shoulder and Elbow Surgery; AJSM = American Journal of Sports Medicine; JPO = Journal of Pediatric Orthopaedics.
