1 Values are presented as the mean ± standard deviation, percentage, or median (range).2 Dry body weight (in HD patients only).∗ Significant difference between groups, according to an independent t-test or chi-square test (p < 0.05). BMI: body mass index, hs-CRP: high-sensitivity C-reactive protein, GNRI: geriatric nutritional risk index, TEE: total energy expenditure, and HOMA-IR: homeostatic model assessment insulin resistance.
