Fig 2. Posterior estimates (posterior mean and 95% credible interval represented by the dot and the vertical interval, respectively) of the PR of the socioeconomic variables on mean SMI prevalence estimated from the full model.

For all 5 covariates, the estimated covariate effect greater than 1 suggests an LSOA with a larger covariate value (e.g., a higher percentage of minority ethnic groups) was associated with a higher SMI prevalence. An estimate with its 95% CI excluding 1 indicates a high certainty that a covariate-outcome association exists. LSOA, Lower Layer Super Output Area; PR, prevalence ratio; SMI, serious mental illness.
