Fig. 4From: Micro-structural white matter abnormalities in new daily persistent headache: a DTI study using TBSS analysisWhite matter regions (warm color: yellow–red) showed increased radial diffusion (RD) values in patients with NDPH compared to HC group (P FWE < 0.05). The white matter regions with green color represented RD skeleton. Note: NDPH, new daily persistent headache; HC: healthy control; L: left; R: rightBack to article page
