Personalized Medicine in Psoriasis - A Long Road Ahead?
Article in Psoriasis (Auckland, N.Z.), 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
Background: Biologic therapies targeting IL‑17 and IL‑23 have revolutionized psoriasis management, enabling rapid and durable disease control. Yet treatment selection still follows a trial‑and‑error approach, and clinically validated biomarkers for personalization remain absent. Objective: To outline current challenges in biomarker development for psoriasis and describe the design and aims of the PICASSO prospective cohort as a platform for future personalized medicine. Current Challenges: Despite evidence that IL‑17/IL‑23 inhibitors may induce disease modification through effects on effector, memory, and regulatory immune cells, reliable predictive or prognostic biomarkers have not emerged. Barriers include complex pathogenesis, universally high biologic efficacy reducing need for stratification, inconsistent findings from genetic or transcriptomic studies, and the multifactorial nature of comorbidities. Methods Picasso ProspectIve Cohort psoriASiS FOllow-Up: PICASSO is a 10‑year prospective biobank/registry enrolling patients within three years of disease onset. Biological samples are longitudinally linked to clinical and epidemiological data, with follow‑ups every 2.5 years. The ultimate aim is to identify biomarkers predicting disease trajectory. Conclusion: Personalized psoriasis care requires biomarkers predicting progression and comorbidity risk. PICASSO represents a step toward disease‑modifying, preventive precision medicine.
