Prevalence of CCSVI and small IJV as a function of EDSS (EDSS < 6 vs. EDSS ≥ 6). Shows prevalence of A) CCSVI, CCSVI + n = 7/25 with EDSS ≥ 6, (*χ2, p = 0.002), and B) small IJV, sIJV + n = 15/ 25 MS patients with EDSS ≥ 6 (*χ2, p = 0.00001) in MS patients categorized by functional disability (EDSS < 6 vs. EDSS ≥ 6).
