BMI, body mass index; CVR score, cardiovascular risk score; EQ-VAS, European quality of life—visual analogue scale (subjective health status);

HDL cholesterol, high density lipoprotein cholesterol; CI, confidence interval; n, number; PAM13-D, German version of Patient Activation Measure questionnaire;

T0, time point of study inclusion (baseline); T1, time point after four months (follow-up)

*1 Adjusted means

*2 Primary endpoint patient activation (PAM13-D), adjusted for PAM13-D at T0, CVR score at T0, and treating primary care physician;

PAM13-D scores from 0 (lowest level of patient activation) to 100 (highest level of patient activation)

*3 Secondary endpoint EQ-VAS, adjusted for EQ-VAS at T0, CVR score at T0, and treating primary care physician;

EQ-VAS scores from 0 (worst health) to 100 (best health)

*4 Additional endpoints, adjusted for the respective endpoint at T0 and treating primary care physician

*5 Effect size calculated as the difference of the adjusted means divided by the square root of the residual variance; absolute values of 0.5–0.8 can be interpreted as moderate effects
