The exposure-response curve for PM<jats:sub>2.5<\/jats:sub> showed a sharp rise after an initial decline at lower concentrations, which may be a model artifact. Stratified analyses revealed stronger associations in the younger population and a significant association between PM<jats:sub>2.5<\/jats:sub> exposure and fracture risk in males.
