Effect of contextual income, measured on different scales, on mental disorders due to psychoactive substance use and neurotic disorders. Results were obtained from hierarchical geostatistical models adjusted for individual covariates* for all people aged 40–69 years in Malmö, Sweden, in 2001

| *The models were adjusted for age, gender, marital status, education, and income. †Contextual income variables measured on different scales were introduced into separate models. ‡The deviance information criterion (DIC) can be used to compare different models estimated for a similar mental health outcome, but not to compare models for different outcomes. The lower the DIC, the better the fit of the model. | ||||
