Fig. 6 — Group data of path length ratio. Boxplots of path length ratio (PLR) and PLRv (top row) are shown for each of the three groups with vision removed and vision restored. Scatter plots without (middle row) and with (bottom row) vision show the performance in the parameters for stroke cases and controls with 95% prediction intervals of control performance defining normal boundaries (black lines). Both AIS and PVI groups demonstrate increased PLR (a) and PLRv (d) relative to controls. Stroke cases often demonstrated greater PLR (b, c) and PLRv (e, f) across all ages (x-axis)
