Association of class II obesity with postkidney biopsy hematocrit drop. Linear regression analysis showing association of class 2 obesity with hematocrit drop after kidney biopsy. Beta coefficient and 95% confidence intervals are shown. A negative coefficient indicates that there was lesser drop in hematocrit among those with obesity. Model 1 is univariable. Model 2 controls for platelet count, INR, and BUN. Model 3 additionally controls for needle gauge (16 versus 18). CI, confidence interval.
