Fig. 2From: Effect of awake prone position on diaphragmatic thickening fraction in patients assisted by noninvasive ventilation for hypoxemic acute respiratory failure related to novel coronavirus diseaseGeneralized linear mixed model predicted diaphragmatic thickening fractions according to comfort scores, adjusted for body position, i.e., supine versus prone. Generalized linear mixed model predicted diaphragmatic thickening fractions according to comfort scores with 95% confidence intervals, adjusted for body position, i.e., supine (green) versus prone (red), are depicted. Fixed effect comfort score estimate (95% CI) =  − 2.9 (− 5.5 to − 0.4); p = 0.025Back to article page
