Table 4. Heart-rate variability: Poincaré plot analysis (phase domain).
Control group (n = 52) | HIV group (n = 97) | Significance | |
LL (ms) | 360 (188–481) | 353 (255–445) | NS |
LB (ms) | 131 (110–148) | 130 (121–153) | NS |
LSD (ms) | 20 (8–34) | 19 (10–27) | NS |
Values are median (25 percentile-75 percentile).
LL: Length of Lorenz plot; LB: Width of Lorenz plot; and LSD: Difference between geometric and mass center.
Statistical comparison was performed by Mann-Whitney test.
