Notes: Data are expressed as mean ± standard deviation for variables with normal distribution and median (interquartile range) for variables with non-normal distribution. P-values were tested using Student’s t-test for variables with normal distribution and Mann–Whitney U-test for variables with non-normal distribution.
Abbreviations: HPs, healthy participants; HD, hemodialysis; VFA, visceral fat area; SFA, subcutaneous fat area; BMD, bone mineral density.
