Correlations between the percentages of γδ T cell subsets and disability in IFN-β-treated MS patients. a–d Correlation between the percentage of Vδ1⁻Vδ2⁻Vγ9⁺ cells in γδ T cells and EDSS scores (a, b) or MSSS (c, d) at examination in NEDA (a, c) and EDA (e, f) groups of IFN-β-treated MS patients. e–h Correlation between the percentage of Vδ1⁻Vδ2⁻Vγ9⁻ cells in Vδ1⁻Vδ2⁻ γδ T cells and EDSS scores (e, f) or MSSS (g, h) at examination in NEDA (e, g) and EDA (f, h) groups of IFN-β-treated MS patients. Correlations were calculated using Spearman’s rank correlation coefficient. EDA evidence of disease activity, EDSS Expanded Disability Status Scale, IFN-β interferon-β, MS multiple sclerosis, MSSS multiple sclerosis severity score, NEDA no-evidence of disease activity
