Preoperative nomogram predicting 90-day mortality in patients ≥75 years of age undergoing radical cystectomy. Points are calculated independently for each of the four variables (“contributed points”), and the sum of the points (“total points”) is used to calculate the 90-day survival probability. For example, an 83 year-old patient with muscle-invasive cancer, CCI of 2, and preoperative albumin of 2.9 g/dL (100 points) would have a 90-day survival probability of 50%.
