β-actin gene-based detection of serum cfDNA. DNA isolated from sera of healthy individuals (CTR), RA and RRMS patients was subjected to qPCR analysis with primers for the β-actin205 amplicon (a). The bars indicate the median with interquartile range. **indicates p < 0.0001; ns indicates not significant. A ROC analysis was performed to discriminate RA patients from healthy controls (b)
