Nomograms for Predicting Graft Function and Survival in Living Donor Kidney Transplantation Based on the UNOS Registry

A, nomogram predicting 1-year eGFR based on pretransplant information. Instructions: first row (Points) is point assignment for each variable. Rows 2 to 19 represent variables included in model. For each donor-recipient pair each variable is assigned point value (uppermost scale, points). Vertical line is made between appropriate variable value and points line. Assigned points for all variables are summed and total is found in row 20 (Total Points). Once total is located vertical line is made between total points and final row 21 (1-Year predicted eGFR). W, white. B, black. O, other. D, diabetes. G, glomerulonephritis. R, re-transplant. B, calibration curve for internal validation. Broken line represents performance of ideal nomogram in which predicted outcome corresponds perfectly with actual ones. Solid line represents performance of constructed nomogram. Bootstrap corrected r-square of nomogram was 0.131.

A, nomogram predicting 5-year graft survival probability based on pretransplant information. Instructions: first row (Points) is point assignment for each variable. Rows 2 to 19 represent variables included in model. For each donor-recipient pair each variable is assigned point value (uppermost scale, points). Vertical line is made between appropriate variable value and points line. Assigned points for all variables are summed and total is found in row 20 (Total Points). Once total is located vertical line is made between total points and final row 21 (5-Year Graft Survival Probability). W, white. B, black. O, other. D, diabetes. G, glomerulonephritis. R, re-transplant. B, calibration curve for internal validation. Diagonal line represents performance of ideal nomogram in which predicted outcome corresponds perfectly with actual ones. Line with vertical boxes represents performance of constructed nomogram. Vertical boxes indicate 95% confidence intervals based on bootstrapping analysis. Concordance index of nomogram was 0.71.

A, nomogram predicting 5-year graft survival based on information at before transplant and 6 months after transplant. Instructions: first row (Points) is point assignment for each variable. Rows 2 to 22 represent variables included in model. For each donor-recipient pair each variable is assigned point value (uppermost scale, points). Vertical line is made between appropriate variable value and points line. Assigned points for all variables are summed and total is found in row 23 (Total Points). Once total is located vertical line is made between total points and final row 24 (5-Year Graft Survival Probability). W, white. B, black. O, other. D, diabetes. G, glomerulonephritis. R, re-transplant. B, calibration curve for internal validation. Diagonal line represents performance of ideal nomogram in which predicted outcome corresponds perfectly with actual ones. Line with vertical boxes represents performance of constructed nomogram. Vertical boxes indicate 95% confidence intervals based on bootstrapping analysis. Concordance index of this nomogram was 0.784.
