^aFor each quartile, the number displayed represents the significance test for chi-square analysis comparing the proportion of each patient- and provider-level covariate by type of urinary diversion.

^bPropensity score quartile 1 contains subjects with the lowest likelihood of receiving a continent diversion, and quartile 4 contains those with the highest likelihood.

^cWithin this propensity score quartile, no subject had a history of this comorbid condition.
