Relative risks (RRs) (intervention group v. control group) and 95% confidence intervals (CIs) of a reliable improvement at 3 months compared with baseline, by domain of self-management. Values greater than 1.0 indicate more patients in the intervention group had reliable improvement in a domain of self-management compared with the control group. The difference between the 2 groups is significant when the value of no difference (RR = 1.0) is not included in the CI.
