Joint Involvement Pattern Predicts Treatment Response in Early RA
A combined individual-patient-data analysis of the NORD-STAR and BeSt trials shows that where early RA is distributed carries prognostic signal: hand-dominant disease (JIP-Hand) predicts better treatment response and polyarthritis (JIP-Poly) worse — independent of sex and serology, and equally across csDMARDs and bDMARDs, with ACPA/RF showing no association with short-term activity response.
