BACKGROUND In the current study, we aimed to investigate the effect of smoking on inadequate response to Methotrexate (MTX-IR) in rheumatoid arthritis (RA) patients.

Two independent reviewers assessed the risk of bias and the certainty of the evidence using ROBINS-I and grades of recommendation, assessment, development, and evaluation (GRADE) tools, respectively.
