The success rate at first and third months were assessed by the point-prevalence regarding the previous week. Intention-to-treat analysis was used.

Findings: Success rate in the first month was 65.9% for intervention group and 40.9% in the control group; for the third month it was 50.0% in the intervention group and 30.7% in the control group. Being in the intervention group increased the success rate by 3,50 (1,30-9,44) times in the first month and 2,50 (1,08-6,40) times in the third month.
