Fig. 5From: Human limb skeletal muscle wasting and architectural remodeling during five to ten days intubation and ventilation in critical care – an observational study using ultrasoundPennation angle of vastus lateralis on day 1 and change in angle on day 5. Correlation tested using Pearson’s product–moment correlation coefficient. A significant correlation was noted between the pennation angle on admission, and the percentage change in pennation angle on day 5Back to article page
