| Metabolite | Control Group (n = 10) | Neonatal Encephalopathy Infants (n = 17) | P Values | |||
|---|---|---|---|---|---|---|
| Normal/Mild Outcome (n = 10) | Severe/Fatal Outcome (n = 7) | Control Versus Normal/Mild Outcome | Control Versus Severe/Fatal Outcome | Normal/Mild Outcome Versus Severe/Fatal Outcome | ||
| Lac | 1.28 (0.44) | 1.39 (0.63) | 1.28 (0.56) | .68 | 1.00 | .72 |
| NAA | 1.31 (0.31) | 1.27 (0.12) | 1.16 (0.14) | .52 | .26 | .09 |
| Cho | 1.18 (0.22) | 1.13 (0.16) | 1.11 (0.18) | .62 | .53 | .78 |

Note:—Lac indicates lactate; NAA, N-acetylaspartate; Cho, choline; Cr, creatine. Values are mean (SD) and median (interquartile range) as appropriate.
