  1. The rate is the proportion of the sample from the respective year. The absolute number of in-patients within each category is a linear extrapolation from the sample to the target population (Germany). Rate and number are standardized for the average number of secondary diagnoses in 2006. The total rate shows the weighted average for the years 2003 to 2007.
