Blood cell count in black and white men before RP

	All men Mean (SD)	Black men Mean (SD)	White men Mean (SD)	p-value*
Neutrophils (1000 cell/ul)	4.04 (1.53)	3.48 (1.49)	4.47 (1.42)	<0.001
Lymphocytes (1000 cells/ul)	1.95 (0.63)	2.04 (0.67)	1.88 (0.59)	<0.001
Platelets (1000 cells/ul)	233.15 (55.92)	232.65 (55.41)	233.54 (56.32)	0.73
NLR (neutrophil-lymphocytes ratio)	2.24 (1.12)	1.84 (1.03)	2.54 (1.10)	<0.001
PLR (platelet-lymphocyte ratio)	129.10 (49.70)	123.70 (48.36)	133.25 (50.32)	<0.001

^*p-values for the differences between black and white men were computed using rank sum test

Note: The top 5% of values for each CBC variable were excluded in calculating summary statistics
