Linear multivariable models.

Results of fitted linear models, each adjusting for additional variable, with its β coefficients and 95% CI (corresponding to psychiatric disease presence), statistics (t and p values), and model fit measures (log-likelihood, Akaike and Bayesian Information Criteria). Model 1: Unadjusted for psychiatric disease; Model 2: Adjusted for age above 40 years; Model 3: Adjusted for age above 40 years, sexual intercourse in the last four weeks; Model 4: Adjusted for age above 40 years, sexual intercourse in last four weeks, physical exercise more than 150 minutes/week. Model 5: Previous variables and sexual orientation; Model 6: Previous variables + steady partners; Model 7 (full model): previous variables + menstrual cycle.
