Notes: A hazard ratio less than 1.0 indicates decreased acceptance for kidney transplant for a given point in time. All variables included in Gray’s Cox multivariable regression model are included in this table.
1
Only shown for covariates which met the proportional hazards assumption.
2
Only shown for covariates which did not meet the proportional hazards assumption.

Additional information (ie, plot of smoothed log(HR) function with 95% confidence bands) for the covariates not meeting the proportional hazards assumption is reflected in Supplementary Figures 1–3 (available online).
