Data are presented as mean ± standard deviation or median (interquartile range) for continuous variables and number (%) of patients for categorical variables.
Continuous variables were compared using a one-way analysis of variance and Kruskal-Wallis testing. A Cochran-Armitage trend test was used to compare more than two categories.
CI, confidence interval; eGFR, estimated glomerular filtration rate.
Cox proportional hazard models were adjusted for the serum osteoprotegerin level, age, sex, presence of diabetes mellitus and hypertension, low-density lipoprotein cholesterol, serum albumin, calcium, proteinuria (protein-to-creatinine ratio), C-reactive protein, serum klotho level, and time-stratified eGFR.
