  1. * Subcohort of patients at work with nonmissing data (n = 187), standardised to German company health insurance population, stratified by calendar year, sex and age.
  2. 1 time period with regard to the time of beginning of the treatment of the patient (-3 = observation year three years before, 1 = first observation year after treatment and so one);
  3. 2 95% confidence intervall;
  4. 3 75. Percentile, a SSR-Q3 of 1.0 means that in that given observation year 25% of the observed patients show the same sick leave durations as in their corresponding reference group regarding age and gender;
  5. 4 P-value contrasted to the observation year -1.
