Figure 2

The region of interest (ROI) analyzed was chosen at the injury site (tendon midsubstance) to quantify the (A) circular standard deviation (CSD), and (B) echogenicity.

*Solid lines indicate significant differences (p<0.0083) and dashed lines indicate trends (p<0.017). Error bars indicate standard deviation.
