Incident chronic kidney disease in relation to later-life exposure to PM2.5 constituents and extreme temperature events in a national cohort study

BACKGROUND: components and extreme temperature events (ETEs) with the incidence of chronic kidney disease (CKD). METHODS: and ETEs exposures were assessed using interaction terms and the metric of relative excess risk due to interaction (RERI). RESULTS: constituents in triggering CKD events (HR >1 for interaction and RERI >0), under multiple definitions of cold spells. CONCLUSIONS: pollution.
