Fig. 1: Serum levels of FABP7 were higher in SPMS and showed correlation with EDSS score and brain volumetrics in MS patients.

a, b Bars (mean ± SD) show serum levels of (a) FABP7 and (b) FABP4 in RRMS, and age-matched healthy controls (HC1) and in SPMS and age-matched healthy controls (HC2). One-way ANOVA was performed following correction with Šidák multiple comparison test, and P-values are shown above the comparisons (n = 32 of each group). c A negative correlation of FABP7 with BPF (n = 34). d, e A positive correlation of FABP7 with T1LV and T2LV (n = 34). f A positive correlation of serum FABP7 with EDSS score (n = 98). Two-sided simple linear regression analysis was performed for correlation and shown as a regression line (shaded area represents error of the regression line), data is adjusted for age and sex, and p-values were adjusted using Holm’s correction for (c–f). RRMS Relapsing remitting MS, SPMS Secondary progressive MS, BPF Brain Parenchymal Fraction, T1LV whole brain T1 hypointense white matter lesion volume, T2LV whole brain T2 hyperintense white matter lesion volume.
