aRepeated measures multivariate analysis of covariance was used to examine the efficacy of the mobile app for gynecologic cancer support program on primary and secondary health outcomes at 12 weeks (T1) and 24 weeks (T2), adjusted by baseline corresponding health outcomes.
bAdjusted effect sizes were calculated by dividing the between-group difference of the postintervention means (adjusted for baseline values) by the pooled standard deviation [41].
