From: Renal anemia and hyporesponsiveness to ESA for preservation of residual kidney function in patients undergoing peritoneal dialysis

Non-linear association between ESA resistance index and risk of anuria. Non-linear estimation of residual urine output was demonstrated using restricted cubic spline analysis with three knots at the 10th, 50th, and 90th percentiles of ERI in all patients (A) and in those who were administered ESA (B). The reference category was placed on the median values of ERI, 2.47 (A) and 2.68 (B). A multivariable regression model was adjusted for the variables in Model 5. ESA, erythropoiesis-stimulating agent; ERI, ESA resistance index.
