Comparative effectiveness and predictors of remission between adalimumab and ixekizumab in patients with psoriatic arthritis: findings from the 'AIRE' multicentre study.
Observational study in RMD open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTumour necrosis factor α (TNFi) and interleukin 17 (IL-17) inhibitors have demonstrated efficacy and safety in psoriatic arthritis (PsA) therapy through head-to-head randomised controlled trials, but evidence from real-world clinical practice (RWE) remains limited.
methodsAdalimumab vs Ixekizumab Real-world Effectiveness is a multicentre cohort study, aimed at comparing the effectiveness of these drugs in a 'real-world' PsA population. The primary outcome consisted of mixed-effects models comparing Disease Activity in Psoriatic Arthritis (DAPSA) and Psoriasis Areas and Severity Index (PASI) over 12 months in both treatment groups. Remission outcomes (DAPSA; Minimal Disease Activity (MDA)) were analysed using time-dependent Cox models adjusted for confounders.
resultsA total of 437 patients (42% on adalimumab (ADA); 57% on ixekizumab (IXE)) were enrolled. At baseline, the ADA group mainly showed axial and nail involvement, while the IXE group was mostly biologic disease-modifying antirheumatic drug (bDMARD)-experienced and had higher C reactive protein levels and worse functional status.The DAPSA score improved in both groups, and between-treatment differences in DAPSA pathways over time were not significant. Probabilities of achieving DAPSA remission or MDA did not differ by drug at 12 months. PASI improved similarly in both groups, but IXE showed a greater early reduction from baseline at 3 months. DAPSA remission and MDA were primarily associated with male sex, absence of nail psoriasis, higher PASI, fewer prior bDMARDs and better functional status.
conclusionsThis RWE study showed that ADA and IXE provide similar 12-month joint outcomes, while IXE showed a faster skin response. Baseline demographic and clinical features affect the chance of remission, highlighting the importance of personalised treat-to-target approaches in PsA.
