Statistics for the lines made to fit arch artery trends. The equation of the curve, R² value, significance of the slope and P-value are displayed. Note how not all the experimental curves are significantly non-zero while the model curves are all significantly non-zero. Exp- experiment, Occl- Occluded, Cntrl – control.
