Extended Data Fig. 2: Mean absolute correlation for Cox proportional hazards model and weighted Cox proportional hazards model.

Covariate balance was evaluated using mean AC, with AC < 0.1 indicating good balancing for covariates included in the analyses. Abbreviations: AC, absolute correlation; PM2.5, particulate matter with diameter <2.5 μm; PM10, particulate matter with diameter 10 μm; NO2, nitrogen dioxide; NOx, nitrogen oxides; BMI, body mass index; TDI, Townsend deprivation index.
