This study seeks to address the question: "How do serum IL-6 levels and the SII, alongside other inflammatory biomarkers, correlate with rheumatoid arthritis severity?" It is hypothesized that elevated IL-6 and SII values will correlate with higher RA severity and that combining these biomarkers will yield a more precise model for predicting disease progression. The gene discussed is IL6; the disease is rheumatoid arthritis.
