Summary of individual glomerular volume (IGV) values: sex comparisons in African and Caucasian Americans

		Females			Model 1 for males (matched to females by age and N_glom)			Model 2 for males (matched to females by age, N_glom and BSA)

N_glom extremes: High or Low based on extremes of the female N_glom distribution; Mean IGV represents the mean value of 180 measured glomeruli per group (30 glomeruli per subject, 6 subjects per group); SD: standard deviation; NS: not statistically significant.

***P < 0.001 and **P < 0.01 in bold; ^NSP > 0.05; all statistical comparisons were performed between females and model 1 for males and between females and model 2 for males.
