A scatter plot shows the relationships between muscularis propria inner layer smooth muscle hypertrophy histology scores and both median bowel wall and overall right lower quadrant (RLQ) shear wave speed (SWS) measurements with differing amounts of abdominal strain, as presented in Table 4 (n=18). Least square fit lines show that smooth muscle proliferation (x-axis, based on pathologist scoring) is associated with increasing bowel wall and overall right lower quadrant stiffness. Interestingly, the fit lines for bowel wall and overall right lower quadrant SWS measurements obtained using 20% abdominal strain are nearly identical, having the steepest slopes. This suggests that both of these particular methods provide similar levels of discrimination of differing amounts of bowel wall muscularis propria inner layer smooth muscle hypertrophy
