Post-marketing Re-evaluation of WangBi Granules for Rheumatoid Arthritis

Study Overview
=================
Brief Summary
-----------------
The group used a randomized controlled trial to conduct a post-marketing re-evaluation study of Wangbi granules. The study was conducted to observe the degree of clinical remission in rheumatoid arthritis patients with low disease activity after standard methotrexate and tofacitinib citrate treatment, using a combination of Chinese and Western medicine treatment with Wangbi granules. The study aims to provide evidence-based medical evidence to improve the clinical efficacy of rheumatoid arthritis, enhance the depth of remission, and improve the diagnosis and treatment of rheumatoid arthritis.
