TABLE 3.

Plasma concentrations of biomarkers of inflammation in OC users vs. nonusers with adequate (PLP = 31–70 nmol/L) and low (PLP ≤30 nmol/L) vitamin B-6 status¹

	Adequate vitamin B-6 status		Low vitamin B-6 status
	Nonusers (n = 11)	OC users (n = 93)	Nonusers (n = 11)	OC users (n = 18)
Kyn/Trp	0.022 ± 0.007	0.020 ± 0.005	0.019 ± 0.005	0.021 ± 0.005
Neopterin, nmol/L	6.57 ± 1.39	6.27 ± 2.58	6.81 ± 1.25	5.96 ± 1.42
CRP, mg/L	3.77 ± 4.02	3.77 ± 3.75	1.40 ± 2.39	1.34 ± 1.11

¹Values are means ± SDs. Multivariate ANOVA was performed separately for adequate and low vitamin B-6 status. CRP, C-reactive protein; Kyn, kynurenine; OC, oral contraceptive; PLP, pyridoxal 5′-phosphate.
