Values of SDANN, VLF, HF% and LZC estimated during the first 30 min of the HD session and for the entire HD session. The values are expressed as median (25°, 75° percentiles). Significant values are indicated in bold.
L group: FOpre ≤ 2.5 L; H group: FOpre > 2.5 L; d: diabetic; nd: non diabetic.
Post-hoc comparisons between the four subgroups (Ld vs Lnd, Hd vs Hnd): § P = 0.02 * P = 0.001.
