1 · What the graph read from it

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.

2 · The registry

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

Psoriasis is an immune-mediated inflammatory disease (IMID) impacting more than 40 million people globally and characterized by skin plaques, elevated systemic levels of inflammatory cytokines, and psychosocial burden. Many patients remain undertreated. Available topical and oral treatments are typically less effective than biologic therapies and have safety considerations that may limit long-term use. Tyrosine kinase 2 (TYK2), a Janus kinase (JAK) enzyme, is a validated target in psoriasis and is also being investigated for other IMIDs. TYK2 mediates signaling of interleukin (IL)-23 and IL-17, central proinflammatory cytokines whose dysregulation contributes to chronic inflammation associated with psoriasis, and IL-12 and type I interferons (IFNs). Therefore, selective inhibition of TYK2 offers more targeted immunomodulation vs. broader immunosuppression associated with JAK 1/2/3 inhibition. Envudeucitinib (formerly ESK-001) is a next-generation, oral, allosteric TYK2 inhibitor under investigation for the treatment of psoriasis and systemic lupus erythematosus. Envudeucitinib selectively binds to the unique regulatory domain (JAK homology 2 [JH2]) of TYK2 to induce a conformational change that prevents ATP from binding the catalytic domain (JAK homology 1 [JH1]), thereby inactivating TYK2. This approach avoids adverse events associated with classic JAK inhibition. In preclinical and phase 1 studies, oral administration of envudeucitinib twice daily achieved maximal (90% inhibitory concentration [IC
