Table 1.

Subject demographics separated by presence or absence of hypoglycemia (glucose <46mg/dL) documented within 24 hours after birth. Neonatal seizures includes both clinical and electrographically-confirmed seizures. Medians are compared using the K-sample equality of medians test. Means are compared using the t-test. Proportions are compared using the Fisher exact test.
