a Map of the relative risk (RR) of developing MS in association with average winter PM2.5 levels, after adjustment for degree of urbanization and deprivation index, across the 188 municipalities in the province of Pavia. Darker areas have higher RR values (gradients of grey). b Posterior probabilities (PPs) in association with average winter PM2.5 levels. The highest PPs were consistently identified in the areas also characterized by the highest RRs
