Table 3.

Self-reported adherence to anticoagulation by treatment arm.

Adherence questions	Control, n (%)		Intervention, n (%)
	Baseline (n=59)	Follow-up (n=56)	Baseline (n=61)	Follow-up (n=57)	Adjusted % difference (95% CI)^a	P value^b
Do you sometimes forget to take (name of anticoagulant medication)?^c	13 (22)	13 (23.2)	17 (27.9)	2 (3.5)	16.6 (2.8 to 30.4)	<.001
Over the past 2 weeks, were there any days you did not take (name of anticoagulant medication)?^c	4 (6.8)	6 (10.7)	11 (18)	2 (3.5)	7.9 (−1.5 to 17.2)	.09

^aEstimate of the adjusted percentage difference (95% CI) of follow-up adherence in the intervention group versus control group from logistic regression model with follow-up adherence as outcome variable, adjusting for baseline adherence as covariate.

^bP value from logistic regression model comparing follow-up adherence between intervention group versus control group with adjustment for baseline adherence.

^cNumbers and percentages reflect the number of participants answering “yes” to each item.
