PG - 271-278 LID - 10.1093/bjd/ljad179 [doi] AB - BACKGROUND: Most information on the comparative effectiveness and survival of methotrexate (MTX) and adalimumab (ADA) in the treatment of psoriasis is from randomized control trials and may not translate to the everyday clinical setting. OBJECTIVES: To determine the real-world effectiveness and survival of MTX and ADA in patients with moderate-to-severe psoriasis registered in the British Association of Dermatologists Biologics and Immunomodulators Register (BADBIR). METHODS: Eligible patients were registered in BADBIR, >/= 16 years of age and receiving a first course of MTX or ADA between September 2007 and December 2021, with >/= 6 months of follow-up. Effectiveness was defined as achieving an absolute Psoriasis Area and Severity Index (PASI) /= 13 weeks after the treatment start date until the stop date. The average treatment effect (ATE) was estimated using inverse probability of treatment weighting with propensity score, including baseline covariates. ATE results were presented as risk ratios (RR). A flexible parametric model was used to estimate adjusted standardized average survival, defined as treatment discontinuation associated with ineffectiveness or the occurrence of adverse events (AEs) at 6, 12 and 24 months. Restricted mean survival time (RMST) at 2 years of treatment exposure was calculated. RESULTS: In total, 6575 patients (median age 44 years; 44% female) were analysed; 2659 (40.4%) were prescribed MTX and 3916 (59.5%) ADA. The proportion of patients achieving PASI
