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.
