TABLE 4.

Partial correlations (N = 131).

Variables	1	2	3	4
(1) HFHRV_log	−
(2) NIM_log	0.535***	−
(3) CRP_log	0.010	-0.833***	−
(4) LTLarb	0.330***	0.300***	-0.135	−

All correlations are controlling for age, sex, WBC, and time since last meal. All correlations are 2-tailed. HFHRV, high frequency component heart rate variability; _log, log10-transformed variable; NIM, vagal neuroimmunomodulation index; CRP, c reactive protein; WBC, white blood cell count; LTL, leukocyte telomere length arbitrary units.
