  • a Total n = 19,799, because only 1-yr survivors are included. HR are relative to people who were receiving HD at day 90 and 1 yr. All of theses risks significantly differed from each other in addition to the HD90/HD365 group. These risks did not significantly interact with BMI categories (P = 0.2 for interaction) or with comorbidity and age (P = 0.14 for interaction).
