Tree canopy clusters that are 100 m2 or more only. The HRs and 95% CIs were estimated for the cumulative risk (1 IQR change in aggregation index, patch density, and area-weighted mean shape index) in the stratified multi-exposure models. Q represents quartiles for socioeconomic position and tertiles for PM10, PLAND, and air temperature. HR=hazard ratio. PLAND=tree canopy cover.
