Guselkumab effectiveness in real-world settings: observations from an Italian multicentre 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
Objectives: Guselkumab is a biologic disease-modifying antirheumatic drug (bDMARD) with proven efficacy for psoriatic arthritis (PsA) in randomized controlled trials. Evidence of its effectiveness from clinical practice remains limited. We evaluated the real-world effectiveness of guselkumab for PsA (primary objective) and identified factors influencing clinical outcomes. Methods: This retrospective, observational, multicentre study enrolled consecutive patients with PsA prescribed guselkumab for joint involvement at 26 Italian rheumatology referral centres. Baseline data included patient history, PsA subtype, treatment history and disease activity. Treatment effectiveness was assessed with Kaplan-Meier curves; Cox proportional hazards analysis identified factors associated with treatment persistence. Results: The study included 278 patients (median age: 57 years [interquartile range, IQR: 50-63]; 64.4% female); median observation 10.7 months (IQR: 5.3-15.9; total: 3332.6 patient-months). Retention rates at 6, 12 and 24 months were 90.4%, 80.0% and 67.8%, respectively. Reasons for discontinuation included primary inefficacy (48% of 54 cases), secondary inefficacy (41%) and skin/mucosal intolerance (4%). Statistically significant factors ( Conclusions: Approximately two-thirds of PsA patients treated with guselkumab remained on therapy after 2 years. Adverse events motivated <10% of discontinuations. Effectiveness was higher in patients with enthesitic or axial PsA and in those without concurrent corticosteroids or csDMARDs, confirming the effectiveness and safety of guselkumab as an optimal choice for monotherapy, particularly in PsA patients with enthesitis, with or without joint impairment, and/or axial involvement.
