Drug retention of TNF versus IL-23 inhibitors in psoriatic arthritis: a multicenter real-life cohort study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by musculoskeletal and cutaneous involvement. While TNF inhibitors (TNFi) are commonly used as first-line biologic therapies, treatment failure is frequent. IL-23 inhibitors (IL23i) represent an alternative mechanism of action (MoA), but direct real-world comparisons between these drug classes remain limited. Objectives: To compare the effectiveness of TNFi versus IL23i in real-life PsA patients. Design: This multicenter retrospective observational study is part of the BIRRA (BIologics Retention Rate Assessment) project. Consecutive patients with PsA-classified according to the CASPAR criteria-were screened across 29 Italian rheumatology referral centers. Methods: We analyzed 1418 therapeutic lines for PsA initiated between 2019 and 2024 across 29 Italian rheumatology centers. Treatment lines were categorized as TNFi or IL23i based on the drug's MoA. Demographic, clinical, and treatment-related data were collected. The primary outcome was treatment retention, evaluated by Kaplan-Meier survival analysis. A Cox proportional hazards model adjusted for a propensity score (PS) was used to account for confounding factors. Results: Among 1418 prescriptions (1270 TNFi; 148 IL23i), IL23i lines were associated with older age, longer disease duration, higher baseline disease activity, and more prior biologic disease-modifying antirheumatic drugs exposure. Despite this, no significant difference in crude retention was observed. After PS adjustment, IL23i prescriptions showed significantly longer treatment retention than TNFi (hazard ratio 0.53; 95% confidence interval: 0.31-0.90; Conclusion: In this real-world cohort, IL23i prescriptions demonstrated comparable treatment persistence compared to TNFi, even in more challenging clinical scenarios. These findings support the inclusion of IL23i as a valid therapeutic option in PsA. Prospective studies are needed to confirm their positioning in treatment algorithms.
