Measures of self-reported health status.

Note: Means and standard deviations are reported for each outcome measure at month 0 and at month 3, 9 and 15 until completion of the study. Means were generated using participants with data at least three time points for the outcome of interest. P-values are based on linear mixed modelling. An increase in the scores of the SF-12 scales means an improvement in the perceived rate of wellbeing.
*P-values are interpreted from the results of comparisons between specific time points. When the p-value interpreted is from the group-by-time interaction effect, the change between two time points for the two groups is compared.
**Bonferroni post-hoc tests were used with significant interactions in the IG (p<.001).
IG = intervention group; CG = control group; PF = physical function; PCS = physical composite score; MCS = mental composite score; SD = standard deviation; CI = confidence interval.
