Logistic regression predicting likelihood of an inactive occupational status (executive functioning and IQ as predictors)

	p-value	OR	95% CI
Executive functions	< 0.001	0.53	0.38–0.76
WAIS-III–IQ	0.183	1.04	0.98–1.10
Constant	0.090	0.01

Occupational status as a dichotomized dependent variable (inactive = 1; active = 0). Executive functions (composite measure) and Full Scale IQ (measured with WAIS-III) as covariates. A test of the full model with the two predictors against the constant-only model was significant (omnibus Chi-square = 21.05, df = 2, p < 0.001.), Cox and Snells R² = 0.20. Nagelkerke’s R² = 0.29. The model correctly classified 81.1% of patients (95.7% of the active patients and 42.3% of the inactive patients were correctly classified, n = 95
