Prediction of primary non-response to methotrexate therapy using demographic, clinical and psychosocial variables: results from the UK Rheumatoid Arthritis Medication Study (RAMS). Arthritis Res Ther. 2018;20:147. doi: 10.1186/s13075-018-1645-5.
Sergeant and fellow researchers at the University of Manchester in the UK found that high anxiety, rheumatoid factor (RF) negativity, high tender joint counts, low disease activity scores, and high Health Assessment Questionnaire scores predict non-response to methotrexate (MTX) therapy.1 Thumb through the slides for the details of the study and the take-home points for clinicians.
