Dialysis patients without diabetes and a PCS score
above the median had higher cumulative survival rates
than those with lower PCS scores (log-rank test, χ2 =4.6,
p = 0.03). The cumulative survival rate did not differ in
dialysis patients with diabetes in the different PCS strata
(χ2 =1.0, p = 0.32, n = 299 or χ2 =0.7, p = 0.39. MSC score
