  1. aPersons with continuous health insurance coverage of at least 4 years
  2. bIn one of the health insurances providing data of about 6 million insured persons to GePaRD, the proportion of women 50 years old or older is substantially higher as compared to the general population (32.1% vs. 22.5%). This explains why the gender distribution among patients with advanced CRCs differs from the distribution reported by cancer registries
