Unadjusted and adjusted linear regression on NBME shelf score.

	Unadjusted Association		Adjusted Association
	Coefficient (95% CI)	p-value	Coefficient (95% CI)	p-value
Randomization (Flipped vs Online-Only; n = 104)	1.2 (−1.4, 3.7)	0.37	2.3 (−0.4, 4.8)	0.07
Baseline Examination Score (n = 104)	0.16 (0.04, 0.27)	<0.01	0.19 (0.07, 0.31)	<0.01

Caption: results of univariate and multivariate linear regression on NBME shelf examination scores. Compared to the flipped group, the online-only group scored 1.2 points higher on the NBME shelf exam (p = 0.37) and when adjusting for baseline clinical reasoning examination scores the online-only group score 2.3 points higher on the NBME shelf exam (p = 0.07, η² = 0.09, 95% CI 0.007, 0.199).
