The relationship of histologic alterations and kidney function is altered by race. (A–C) Adjusted means for percent IF, TA, and GS stratified by non-Black race (n=590, gray lines±shaded 95% CI and light gray bars) and Black race (n=160, black lines±shaded 95% CI and black bars). Percentages of IF, TA, and GS modeled using linear regression as a cubic function of eGFR3 adjusted for age, sex, race, HTN, diabetes, and BMI. *P<0.05 compared with the non-Black race group.
