^aP < 0.01. ¹The OR for sex was adjusted for age group. The OR for social deprivation and colectomy was adjusted for age group and sex. The adjusted OR for urban/rural residence and distance from hospital was adjusted for age group, sex and social deprivation; ²Fewer people had 5 years than 1 year follow-up during the 9-year study period, therefore, the number of cases was lower in this Table than in Table 3.
