Health Assessment Questionnaire at One Year Predicts All-Cause Mortality in Patients with Early Rheumatoid Arthritis

Arthritis Rheumatol. 2021 Jul 5. doi: 10.1002/art.41916. Online ahead of print.


With great interest, we read the article by Fatima et al [1], which concluded that higher HAQ and disease activity score at 1 year were significantly associated with all-cause mortality in patients with early rheumatoid arthritis (RA). We agree with the use of discrete multivariate analysis on the cohort dataset. However, we would like to propose some methodological issues of the study.
