Multinomial logistic regression among patients presenting higher OAS (aggressive behavior) scores (Superior to 3).

Variable	Odd ratio	95% Confidence interval	Probability
Male gender	12.8	2.5–64	0.002
History of sexual violence	3.6	1.1–11.7	0.03
Cigarettes/day	1.16	1–1.3	0.02
Fagerström score	1.3	0.8–2	0.04
Cannabis score	1.16	1–1.3	0.12
DETA (alcohol) score	1.2	0.7–2	0.7
Cigarettes/day	1.1	0.9–1.2	0.2

Reference category: patients with OAS scores >3, Likelihood ratio χ² = 49.8, df = 12, p < 0.0001, 81% of the observations are classified by the model, sensitivity = 67%, specificity = 86%.
