Table 3 Hazard ratios of dropout in regard to baseline characteristics

	Exposed	Reference	Hazard ratio	P value	Confidence Interval
Gender	Girl	Boy	1.10	0.60	0.77; 1.58
Age	Below median	Above median	0.72	0.08	0.51; 1.04
SES group	Group 4 and 5	Group 1, 2, and 3	1.22	0.29	0.85; 1.76
Family structure	Disrupted family	Nuclear family	0.98	0.91	0.66; 1.48
Parental BMI	Obese parents	Non obese parents	1.27	0.29	0.81; 1.99
Co-morbidity	Present	Not present	1.03	0.87	0.71; 1.49
Referral	Pediatric dep.	School- and community based doctors	0.80	0.28	0.53; 1.20
Baseline BMI SDS	Above median	Below median	0.85	0.38	0.59; 1.22
Puberty, boys	Present	Not present	1.79	0.10	0.88; 3.61
Puberty, girls	Present	Not present	0.98	0.94	0.58; 1.65
Longitudinal BMI SDS	Higher than baseline	Lower than baseline	1.38	0.15	0.89; 2.14
Between-visits BMI SDS	Higher than previous visit	Lower than previous visit	1.08	0.72	0.72; 1.63

The hazard ratio compares the risk among the exposed compared to the reference, e.g. girls have a 10% increased risk of dropping out compared to boys.
