Table 4 Single- and multi-exposure ordinal regression models in the total study sample of associations between occupational, sociodemographic- and life-style factors and self-efficacy at baseline and levels of burnout at follow-up (level 0 = reference), estimated with Ordinal Regression, with p-values, odds ratios (OR) and 95% confidence intervals (CI). In the last step, the multi-exposure model was adjusted for burnout (level 0–3) at baseline
