Fig 4.

Boxplots of diffusion (minimum MD, FA, CL, CP, and CS) and perfusion (maximum rCBV) characteristics for patients with posttreatment glioblastomas in TP (gray), PsP (white), and mixed tumor (dotted). The solid line inside each box represents the median value, while the edges represent the 25th and 75th percentiles. The straight line (bars) on each box indicates the range of data distribution. Circles represent outliers (values >1.5 box length from the 75th/25th percentiles). The asterisk indicates a significant difference (P < .05) for group comparison.
