^aEach final model also adjusted for: exposure to flooding, age, deprivation (IMD quintile), Local Authority, educational attainment, employment status, ethnicity, marital status, and pre-existing illness (not shown). Final overall main effects model also adjusted for sex.

Notes: Secondary stressors displayed are those statistically significant in increasing the model fit of the data. Those not increasing goodness of fit of the model are displayed as “Not included in final model”.
