Shown are boxplots of FpV, FA, and MD values of the whole ipsilateral and contralateral pyramidal tracts (A, B, and C, respectively). The horizontal lines are the medians, and the ends of the boxes are the lower and upper quartiles (25th and 75th percentiles). MD values are expressed in units × 10−3 mm2/s. The error bars depict the SD. Overlaid are the P values calculated from a 2-sided paired t test (ns = not significant).
