- aWith three categories, days with missed medication doses did not meet the assumptions of the χ2 test. Because very few patients missed 7 days at any time point (1 in the intervention group at 3 months and at 6 months and 1 in the control group at 6 months), data from 1 to 6 days and 7 days were combined
- bWith continuity correction for 2 × 2 table
- cFisher’s exact test was used for 2 × 2 tables when assumptions of χ2 test were not met
- dCriteria of recommended 150 min/wk considered met if 80 % (120 min) of target achieved
