*2Urban: conglomerations (regions with center of population >300 000 inhabitants or population density ≥300 inhabitants/km 2) and urban areas (regions with center of population >100 000 inhabitants or population density >150 inhabitants/km 2, minimum density 100 inhabitants/km 2); rural: regions with population density <150 inhabitants/km 2 and no center of population >100 000 inhabitants, regions with center of population >100 000 inhabitants and population density ≤100 inhabitants/km 2 (definitions according to the German Federal Institute for Research on Building, Urban Affairs and Spatial Development, [BBSR, Bundesinstitut für Bau-, Stadt- und Raumforschung])
*3At least one coded outpatient diagnosis or main or secondary inpatient diagnosis of a further mental illness excluding depression according to ICD-10-GM, Chapter F during the study period, 1 January 2005 to 31 December 2007.
*4At least one coded outpatient diagnosis or main or secondary inpatient diagnosis according to ICD-10-GM, Chapter A to E, G to T (excluding G30) during the study period, 1 January 2005 to 31 December 2007.
*5According to the 95% CI there is a significant difference (no overlap of confidence interval) between the figure for the total population with severe depression (index diagnosis 1 January 2005 to 31 December 2007).
*6In decreasing order of frequency of care pathway.
For the total population, the confidence interval was calculated at a 99% significance level on the basis of the sample. For the index population and the subpopulations the confidence interval was calculated at only a 95% significance level, due to the relatively small sample size. 95% CI: 95% confidence interval
