Notes: Number of patients (%) registered in 1) Only the Danish Colorectal Cancer Group (DCCG), 2) Both the DCCG and the Danish National Patient Registry (DNPR) and/or Danish National Pathology Registry (DNPatR), 3) Only the DNPR and/or the DNPatR and 4) the total number of patients registered with synchronous peritoneal metastases. The Completeness of the registrations in the DNPR and/or the DNPatR: Number of patients registered in the both the DCCG and the DNPR and/or DNPatR (numerator), divided by the number registered in the DCCG (denominator).
