*Results are presented as mean differences or ORs, with 95% CIs and p values, calculated using mixed effects linear regression or logistic regression with robust SEs, allowing for clustering effect and rural versus urban practice location; ICCs for outcomes at baseline were estimated using one-way analysis of variance.
†CAS total score ≥7.
‡HADS subscale score ≥8.
§PCL-C score ≥50; not measured at baseline.
¶Experienced at least physical symptoms on checklist, in the past 4 weeks; Not measured at baseline.
