Long-Term Efficacy of Tumor Necrosis Factor Inhibitors for the Treatment of Methotrexate-Naïve Rheumatoid Arthritis: Systematic Literature Review and Meta-Analysis.

No significant differences in these outcomes were observed when data from open-label RCTs were considered on their own. Further data on the efficacy of TNFi therapy over ≥ 2 years in patients with methotrexate-naïve RA are required. Plain language summary available for this article.
