For example, consider a 62-year-old PD patient with a history of diabetes, serum albumin of 32 g/L, 1 episode of peritonitis, no catheter-related complications, and normal mental status (SDS = 48, SAS = 45): querying each factor in the nomogram, the patient scores 30 points for age, 40 points for diabetes, 25 points for albumin, 30 points for peritonitis, 0 points for catheter complications, and 10 points for mental status, with a total score of 135. Here, ALB is linked to diabetes mellitus.
