The correlation between serum Epstein–Barr virus (EBV) miRNAs concentration and expanded disability status scale (EDSS) scores and receiver operating characteristic (ROC) analyses. (a,b) Ebv‐miR‐BHRF1‐2‐5p (r
s = 0·62, P = 0·0002) and ebv‐miR‐BHRF1‐3 (r
s = 0·43, P = 0·017) were correlated positively with EDSS scores of MS patients. (c,d) When independently using ebv‐miR‐BHRF1‐2‐5p and ebv‐miR‐BHRF1‐3, the areas under the curve (AUCs) were 0·74 [95% confidence interval (CI) = 0·61–0·86] and 0·72 (95% CI = 0·60–0·85), respectively. (e) ROC curve of ebv‐miR‐BHRF1‐2‐5p combined with ebv‐miR‐BHRF1‐3; the AUC was 0·76 (95% CI = 0·64–0·88).
