CSF BAFF and serum APRIL concentration
OMS severity and duration category. (A) Dot plot comparison of BAFF versus OMS severity in all ACTH/steroid groups versus all other OMS groups. Asterisk denotes P < 0.05 by two-tailed t tests within categories. Severity categories were pre-defined based on total score as mild (0–12), moderate (13–24), or severe (25–36). Between-category comparisons were made by ANOVA and Kruskal-Wallis tests. (B) Comparison of BAFF versus OMS duration in all ACTH/steroid groups versus all other OMS groups. OMS duration was pre-defined as acute (0 to 3 months), subacute (>3 months to 1 year), or chronic (>1 year). (C) Serum APRIL concentrations versus OMS severity in all IVIg groups versus all non-IVIg groups. (D) Serum APRIL versus OMS duration in all IVIg groups versus all non-IVIg groups.
