Models (with current or former smokers, separately) are adjusted for all the covariates included in Table 3.

HR hazard ratio, CV cardiovascular, ESKD end-stage-kidney-disease. Number of cigarettes variable was log-transformed due to the skewed distribution. Estimates with p value <0.05 are shown in bold.
