  1. aPer 1000 inhabitants for postcode areas with > = 1000 inhabitants and > = 100 patients. Contacts per disease cluster are calculated using data of 14 GP cooperatives that registered meaningful ICPC-codes for at least 70% of contacts, resulting in data for n = 620 postcode areas.
  2. bConstant: men, age group 20–39, rural area, very high status neighbourhood.
  3. cStatistical significance, bold if P = <.001.
  4. dICC is the intra-class correlation between GP cooperative catchment areas: the relative contribution of GP cooperative catchment area to the residual variance.
