However, using multivariable Cox proportional hazards model analysis, CRS (AHF, type II CRS, type IV CRS) was not significantly and independently associated with patient survival on peritoneal dialysis compared with non-CRS patients after adjusting for other confounding factors, including age (p<0.001), diabetes mellitus (p = 0.07), serum albumin (p = 0.003), serum calcium (p<0.001) and eGFR (p = 0.30) (Table 2). Here, ALB is linked to diabetes mellitus.
