Figure 2
Geographical associations of the multivariable-adjusted percent change in the glomerular filtration rate estimated from serum creatinine (ΔeGFR) at the individual level (A) or aggregated per municipality (B) with PM2.5 air pollution contours. Grey lines indicate borders of municipalities. Red lines represent the air pollution contours of major roads. The Spearman rank correlation coefficients between percent change in eGFR and the exposure to PM2.5 were − 0.016 (P = 0.69) and − 0.022 (P = 0.94) in the individual and aggregated data, respectively.
