Data are presented as mean ± SD and analyzed using paired Student’s t-tests for the within-group change. Linear regression were used to assess the difference between groups over the length of the study, and are presented as beta, 95% confidence interval, and p-value. All data were adjusted for group (intervention/control) and town cluster. 1 Additional adjustment for age, BMI, smoking, working status, marital status, qualifications, income level, group status (intervention/control), and town clustering.
