Use of Anki to review previous material versus USMLE Step 1 scores. A comparison of USMLE Step 1 scores across groups based on their completion rates indicated a significant difference (H₄ = 10.31, p = .036). Pairwise comparisons indicated the mean score for those reviewing material sometimes was significantly lower than those who reviewed most of the time (p = .010) and always (p = .013)
