  1. A negative SMBQ score change indicates reduced burnout level.
  2. aAdjustments for age, sex, socioeconomic index, and social integration.
  3. refThis category is considered the reference (unexposed) category in the analysis.
  4. The overall mean SMBQ score change in the cohort was −0.15.
  5. Unemployed persons were not included in analyses regarding job strain, demands, control or job insecurity (risk of unemployment, new job possibilities).
