Figure 4.

Comparison of (a) maternal age; (b) BMI before pregnancy; (c) gestational age at diagnosis; and (d) time from diagnosis to childbirth. Values were compared between treatments: monitoring, insufflation of oxygen (O²), non-invasive ventilation (NIV), invasive ventilation, extracorporeal membrane oxygenation (ECMO), and body mass index (BMI). Statistically significant differences were observed for “Gestational age at diagnosis” (p = 0.02) and “Time from diagnosis to childbirth” (p = 0.00034).
