Assessment of patient satisfaction with anticoagulation treatment using ACTS among patients randomized to apixaban or warfarin. Shown is a comparison of patient satisfaction with anticoagulation treatment assessment measured with a validated assessment tool (ACTS) at the shown time points. The midline in each box represents the median, and the top and the bottom of each box represent the cutoffs of the interquartile range. The whiskers represent 1.5 times the interquartile range, and outliers are represented as dots. Apixaban was significantly favored over warfarin at every interval assessment.
