Fig. 6From: Human limb skeletal muscle wasting and architectural remodeling during five to ten days intubation and ventilation in critical care – an observational study using ultrasoundChanges in muscle thickness and pennation angle on day 5 in the vastus lateralis muscle. Correlation tested using Pearson’s product–moment correlation coefficient. On day 5, a significant relationship was observed between the change in muscle thickness and the change in pennation angleBack to article page
