aAll participants had measured variables including 2 participants who did not complete baseline self-report surveys.
bModel coefficients and P values were obtained from analysis of covariance models adjusting for baseline values, general practitioner clinic, and gender. Missing baseline and follow-up values were imputed to create five datasets and results were pooled using Rubin’s rules.
