Therefore, the purpose of this randomized controlled trial was to evaluate the long-term efficacy and safety of this treatment.MethodsThis was a prospective, double-blind, single-simulation, randomized controlled trial investigating the efficacy and safety of BQC in combination with Methotrexate in the treatment of RA, and was approved by the Clinical Research Ethics Committee of the hospital. Patients were randomized in a 1:1 ratio to either the observation or control group and were respectively followed up for 6 months after receiving 12 weeks of treatment. The observation indexes included: total effective rate, DAS-28 score, inflammatory indexes, and adverse reactions. Finally, the collected data was statistically analyzed by SPSS version 18.0.DiscussionThis study evaluated the long-term efficacy of BQC in combination with Methotrexate in the treatment of RA. The trial results of this study will provide new ideas for choosing a combination of Chinese and Western medicine protocols for the treatment of RA.Trial RegistrationOSF Registration number: DOI 10.17605/OSF.IO/U85GX.Copyright © 2021 the Author(s).
