Stability and predictive value of anti-JCV antibody index in multiple sclerosis: A 6-year longitudinal study
Fig 5
Percentages of patients switching between different anti-JCV antibody index categories.
(A) Percentage of patients with anti-JCV antibody index ≤0.9 at baseline (n = 66) switching to higher index categories at least once during follow-up. (B) Percentage of patients with positive anti-JCV serostatus and antibody index ≤0.9 at baseline (n = 23) switching to higher index categories at least once during follow-up. (C) Percentage of patients with anti-JCV antibody index >0.9 and ≤1.5 at baseline (n = 19) switching to higher or lower index categories at least once during follow-up. There was no patient remaining within the baseline index category during follow-up. (D) Percentage of patients with anti-JCV antibody index >1.5 at baseline (n = 69) switching to lower index categories at least once during follow-up.
