From: Nocturnal hypoxemia is related to morning negative affectivity in untreated patients with severe obstructive sleep apnea

Figure 1

Changes in positive and negative affectivity in the PANAS. A significant difference was observed between the three groups only in Δ NA (p = 0.0410). There was a significant trend for Δ NA to increase as OSA became more severe (p-trend, p = 0.023). OSA, obstructive sleep apnea; PA, positive affectivity; PANAS, positive and negative affect schedule; NA, negative affectivity; Δ PA, positive affect score on awakening minus positive affectivity score before sleep; Δ NA, negative affect score on awakening minus negative affectivity score before sleep, *: p < 0.05.
