Cox multivariate regression analysis with backward directed stepwise procedure about the effect of diabetes on the risk of late death after pneumonia

Adjusted HR95% CIp Value
Diabetes2.841.35 to 5.990.006
Karnofsky equal or less than 80%4.191.86 to 9.460.001
Age, years1.53*1.00 to 2.340.048

  • The included confounders were age, Karnofsky score equal or less than 80%, elevated plasma NT-proBNP, and plasma urea concentration. Only factors with at least suggestive independent association (p<0.10) with the risk of late death are presented. N=142 (1 patient with and 10 patients without diabetes were excluded due to lack of urea measurements).

  • *HR is expressed per quartile.
