Tests for proportional hazards assumption concerning cardiovascular mortality.
View PDFScaled Schoenfeld residuals for the factor smoke concerning cardiovascular mortality.
Legend: Under the proportional hazards assumption, the residuals are constant over time. For the factor smoke, residuals are decreasing. Therefore a time dependent term was used for the factor smoke in the final model.

Legend: To validate the model of the main text (table 3a) we fitted three additional models: In alternative model 1, variables were included as confounders in a multivariable Cox model if the change in the Chi-Square statistics of the BMI*GFR interaction term exceeded 10%. Contrasts were calculated identically to Table 3a of the main paper. Wald test for the effect size of the BMI*GFR interaction term: P = 0.0001

Legend: To validate the model of the main text (table 3a) we fitted three additional models: For alternative model 2 a propensity score was created by logistic regression of cardiovascular death on all potential confounders. Alternative model 2 uses this propensity score in a Cox regression model stratified by quintiles of the propensity score. Contrasts were calculated identically to Table 3a of the main paper. Wald test for the effect size of the BMI*GFR interaction term: P = 0.0070.

Legend: To validate the model of the main text (table 3a) we fitted three additional models: For alternative model 2 a propensity score was created by logistic regression of cardiovascular death on all potential confounders. Alternative model 3 uses this propensity score as time dependent covariable in a Cox regression model. Contrasts were calculated identically to Table 3a of the main paper. Wald test for the effect size of the BMI*GFR interaction term: P = 0.0001.
