From: An appraisal of respiratory system compliance in mechanically ventilated covid-19 patients
a Linear regression analysis of arterial partial pressure of oxygen (PaO2/FiO2) and respiratory system compliance (CRS), based on the first measurement obtained within 48 h from commencement of mechanical ventilation, with an interaction of gender and adjusted for body mass index (BMI). No statistically significant association was found between PaO2/FiO2 and CRS (estimate 0.49, 95% CI − 0.09–1.07 p = 0.100). Typical acute respiratory distress syndrome stratification groups [35] (severe, moderate and mild based on levels of hypoxemia) are highlighted in dark, medium and light grey, respectively. b Static respiratory system compliance (CRS) distribution by sex, based on the first measurement obtained within 48 h from commencement of mechanical ventilation. Dashed black lines depict median values for females and males
