Overall Effect of Black Race on Quality Measures

Quality Indicator	p value Overall
Use of RC	0.411
Use of PLND	0.025
Continent Diversion	<0.001
Transfusion	0.053
Any complications	0.013
In-hospital mortality	<0.001
Length of stay	<0.001
Surgeon volume**	0.005
Hospital volume**	<0.001

RC = Radical cystectomy; PLND = Pelvic lymph node dissection

^*p-value for overall effect of Black race on outcome, calculated by an F test of the null hypothesis that coefficients for all terms involving race are zero, including main effect and all interaction terms. Note that the overall effect of race may be significant even when it is not significant in a specific scenario.

^**Models predicting surgeon and hospital volume do not include surgeon or hospital volume as independent variables, whereas other models do include such terms.
