Fig. 4: The relationship between intermittent hypoxemia events and overall time with hypoxemia and hypertension with increasing postnatal age.
From: Neonatal intermittent hypoxemia events are associated with later systemic hypertension

There was a significant (p = 0.02) association between the number of IH events 8–14 days of age and later HTN, but no association at days 15–21 (p = 0.17). There was no association between the percentage of time with hypoxemia and HTN at either postnatal age.
