Table 2.
Blood plasma NO3− and NO2−.
| Measure | Pre-Placebo | Post-Placebo | Pre-NO3− | Post-NO3− | Time × Condition (p-Value) |
|---|---|---|---|---|---|
| Plasma NO3− (μM) | 41 (31–51) |
43 (35–52) |
42 (34–50) |
617 * (572–663) |
<0.001 |
| Plasma NO2− (nM) | 108 (42–174) |
87 (38–135) |
101 (66–136) |
832 * (526–1139) |
<0.001 |
Data are mean (95% confidence interval). p-values refer to the significance of the F-statistic of the two-way (time × condition) repeated measures ANOVA. * Plasma NO3− and NO2− were significantly increased post-NO3− compared to pre-NO3−, while there was no difference pre- to post-placebo.
