From: Brain structural investigation and hippocampal tractography in medication overuse headache: a native space analysis

  MOH patients (n = 14) Healthy controls (n = 15) Significance (p)
Right hippocampus
 Numbers of tracked fibers 536 ± 297 589 ± 263 0.605
 Mean FA 0.65 ± 0.02 0.64 ± 0.03 0.746
 Mean ADC (×1010 m2/s) 5.00 ± 0.21 4.98 ± 0.15 0.794
Left hippocampus
 Numbers of tracked fibers 473 ± 239 660 ± 269 0.045*
 Mean FA 0.64 ± 0.03 0.64 ± 0.03 0.795
 Mean ADC (×1010 m2/s) 5.01 ± 0.18 5.10 ± 0.15 0.177
