The patients were compared with sex-, age-, residence-, and insurance premium\u2013matched controls, and both groups were followed up until the end of 2008 for instances of CRSsNP, defined as ICD-9 codes CRS (473, 473.0, 473.1, 473.2, 473.3, 473.8, and 473.9), excluding NP (471, 471.0, 471.1, 471.8, and 471.9).
