Municipality N=52. N: sample size/individuals. ORs, obtained from bivariate cross-classified multilevel logistic regression models. CI, calculated using SEs that account for the cross-classified nature of the data. Random part omitted. Ref: Reference category. Bold figures: indicate ORs that are significantly different from 1.
*Difference to N=1280 due to missing data in predictors and/or missing data for the cross-classification variable ‘GP-practice by municipality’.
†Alcohol consumption in g/day: DI: female: 0–19.99; male: 0–39.99. DII: female: 20–39.99; male: 40–59.99. DIII: female: >40.0; male: >60.0.
‡Cumulative Illness Rating Scale (CIRS)—severity index: The OR shows the effect on the propensity of enrolment of a one unit difference in the CIRS-severity index, comparing patients with a higher index with patients with a lower index.
§Regional deprivation tertiles (T1-T3) refer to the deprivation of the patient-residential area.
