To determine whether there is a correlation between COMLEX and USMLE scores for osteopathic students applying to the obstetrics and gynecology residency program at Reading Hospital.
Participant selection included osteopathic applicants to the Reading Health System's obstetrics and gynecology residency from 2010 to 2014, including both those students who took only the COMLEX and those who took both the COMLEX and the USMLE. After institutional review board approval, these data were abstracted from ERAS applications and de-identified for analysis.
Eighty-two students took both COMLEX level 1 and USMLE step 1, with mean (standard deviation [SD]) scores of 528.5 (58.4) and 207.5 (14.4), respectively. Seventy-two students took both COMLEX level 2 CE and USMLE step 2 CK, with mean (SD) scores of 543.1 (83.9) and 222.7 (19.2), respectively. USMLE step 1 scores are positively correlated to COMLEX level 1 scores by Spearman correlation (r=0.74, P<.0001). This gives a predictive equation of USMLE step 1 score=108.89+0.1866×COMLEX level 1 score. USMLE step 2 scores are positively correlated to COMLEX level 2 scores by Spearman correlation (r=0.70, P<.0001). This gives a predictive equation of USMLE step 2 CK score=134.1+0.1631×COMLEX level 2 CE score.
These results may suggest that both steps of USMLE scores are strongly correlated with both levels of COMLEX scores. Further research is indicated at other programs to gauge whether these results may be generalizable to a larger group than just the applicants to Reading Hospital.
