  1. Note. Intervention group measured at baseline, 12 weeks, 6 months and 12 months; comparison group measured at baseline and 12 weeks only. Significant p-values (sig p-value) are reported for before-and-after within-group differences at 12 weeks, 6 months and 12 months, and between-group differences at 12 weeks. Sample sizes vary due to missing values.
