B/L Baseline, IQR inter quartile range (25-75th percentile), Med median (not adjusted), M Mean, SE standard error. * indicates a significant result for the corresponding variable. p < 0.05. All Analyses conducted using linear mixed model. AR1 correlation structure adjusted for age, employment, frequency of attendance. ^a PA MET.hours/week of PA. The residuals were skewed; p-value was calculated using a square-root transformation in the LMM. For readability, actual MET. Hour values are reported in this table not the transformed variable. ^bPCS Physical component of the SF-12 (Mean and SE age adjusted). ^c MCS Mental component of the SF-12 (Mean and SE age adjusted)
