  1. CCSVI - chronic cerebrospinal venous insufficiency; VHISS - venous hemodynamic insufficiency score; MS - Multiple Sclerosis; HC - Healthy Controls; RR - Relapsing-Remitting; SP - Secondary Progressive; NS - non significant
  2. The differences between the study groups were tested using Fisher's exact tests and the Mann-Whitney rank sum test. All subjects had the 5 venous hemodynamic criteria correctly assessed.
