Fig 3. Posterior estimates of the effects across the quintiles of each IMD 2015 domains and subdomains on SMI prevalence at national level and major conurbations.

For each index, the reference category was set at the least deprived group, and from left to right, from the less deprived to more deprived quintile. The solid dot represents the posterior mean of the estimated PR and the vertical bar shows the 95% CI. An estimate with its 95% CI covering the value 1 would indicate no difference in SMI prevalence between the corresponding category and the reference category. (Barriers to H&S: barriers to housing and services.) IMD, index of multiple deprivation; PR, prevalence ratio; SMI, serious mental illness.
