TABLE 2.

Difference in average adherence rates (pre- and postrandomization) between usual care and educational intervention groups

Group Mean Standard deviation Difference between EI and UC P value Cohen d effect size
Usual care, n=4 −15.3 25.34 15.66 0.24 0.85
Educational intervention, n=5 0.36 10.28

Adherence was calculated by averaging adherence rates (actual number of openings recorded with the MedMinder system divided by expected number of openings based on prescribed regimen) for each adherence period (ie, 4-week run in and 4-week postrandomization) for EI and UC groups. EI = educational intervention; UC = usual care.
