A Sonographic Quantitative Cutoff Value of Cerebral Venous Outflow in Neurologic Diseases: A Blinded Study of 115 Subjects, via CCSVI in Multiple Sclerosis

"The difference is real. A blinded study in 115 people, published in the American Journal of Neuroradiology, finds that people with MS have altered cerebral venous outflow--the difference value between supine and sitting positions on blood outflow of less than 503.24 was statistically associated with MS compared to other neurological disease and healthy controls." http://www.ncbi.nlm.nih.gov/pubmed/24610905
