Figure 1

Graphical illustration of the magnitude of confounding for one-year estimated glomerular filtration rate (eGFR), showing the regression coefficients for the associations (*** indicating a p-value < 0.0001). The direct effect of the aorto-iliac CaScore on one-year eGFR was −3.3 (95%CI −5.1 to −1.5) and the effect on the confounder (donor age) was 5.0 (95%CI 3.8 to 6.2). The direct effect of the confounder on one-year eGFR was −0.6 (95%CI −0.7 to −0.5), with a bootstrapped indirect effect of −2.9 (95% CI −4.0 to −1.9).
