Table 5 Changes between baseline and follow-up in occupational, sociodemographic^a- and life-style factors and self-efficacy in the total study sample (for each individual calculated as follow-up – baseline); mean values and standard deviation (SD). Single- and multi-exposure models between the changes in the potential risk factors and burnout at follow-up (levels 0–3), estimated with Ordinal Regression, with p-values, odds ratios (OR) and 95% confidence intervals (CI). In the last step, the multi-factor model was adjusted for burnout (level 0–3) at baseline, thereby estimating change versus change associations
