HR, hazard ratio; CI, confidence interval. Other abbreviations are as in Table 1.
In the multivariate model, the following variables were added as independent variables: age, sex, hemoglobin, history of hypertension, cerebral vascular disease, coronary artery disease, albuminuria hemoglobin level, estimated glomerular filtration rate, Wagner classification, and GNRI.
