Gender-specific results of multivariable logistic regression models; Outcomes: alcohol, tobacco, cannabis consumption, and episodes of drunkenness decreased 5 months post-intervention.

	Males		Females
	OR (95% CI)	P	OR (95% CI)	P

Intervention (IG vs. CG)	2.34 (1.44-3.80)	<0.001	1.71 (1.18-2.47)	0.004
Tobacco consumption
Intervention (IG vs. CG)	0.82 (0.41-1.65)	0.581	0.58 (0.25-1.35)	0.206
Cannabis consumption
Intervention (IG vs. CG)	1.64 (0.82-3.31)	0.164	1.07 (0.39-3.00)	0.893
Episodes of drunkenness
Intervention (IG vs. CG)	1.33 (0.77-2.32)	0.310	1.38 (0.93-2.06)	0.110

CG, Control group; CI, Confidence Interval; IG, Intervention group; OR, Odds ratio; p-value (derived by means of a multivariable logistic regression model, adjusted for age and alcohol, tobacco, or cannabis consumption or episodes of drunkenness at baseline; University treated as random effect). Bold values indicate significant effects.
