In post-hoc analyses , illustrated medication schedules led to significantly greater odds of adherence among patients who at baseline had more than eight medications ( OR = 2.2 ; 95 % CI , 1.21 to 4.04 ) or low self-efficacy for managing medications ( OR = 2.15 ; 95 % CI , 1.11 to 4.16 ) ; a trend was present among patients who reported non-adherence at baseline ( OR = 1.89 ; 95 % CI , 0.99 to 3.60 ) .
