  1. All comparisons made with unaffected respondents Adjusted odds ratios are adjusted for age, sex, pre-existing illness, deprivation, local authority, ethnicity, marital, education and employment statuses; Odds ratios with a 95% CI that excludes 1.0 imply significant elevation at p < 0.05 Significance of trend across flooded subgroups is indicated by + at p < 0.1, *at p < 0.05 and **at p < 0.01
