BOCF = baseline observation carried forward; k = No. of primary care practices; MI = multiple imputation; PAM = Patient Activation Measure; PPOS = Patient-Practitioner Orientation Scale.
Note: Data for the intervention and control groups are presented as mean (SD).
↵a Unstandardized coefficients (95% CI) and P value from multilevel linear regression models, with PPOS scores at 12 months as the dependent variable, fixed effects for health care professionals, and random effects for primary care practice (k), with adjustment for the profession (nurse or physician), patients attended per day, and baseline PPOS scores.
↵b Unstandardized coefficients (95% CI) and P value from multilevel linear regression models, with PAM scores at 12 months as the dependent variable, fixed effects for patients, and random effects for professional and primary care practice (k), with adjustment for the rate of obesity and baseline PAM scores.
