Fig 2. A, Whole pontine diameters in the PVL group and control group plotted with respect to age. The whole pontine diameter in the PVL group is smaller than in the control group. B, Basis diameters in the PVL group and control group plotted with respect to age. The basis diameter in the PVL group is smaller than in the control group. C, Tegmentum diameters in the PVL group and control group plotted with respect to age. Tegmentum diameter in the PVL group was smaller than in the control group. D, Corpus callosal lengths in the PVL group and control group plotted with respect to age. Corpus callosal length in the PVL group was smaller than in the control group.
