Efficacy and Safety of Tildrakizumab for Treatment of Moderate-to-Severe Scalp Psoriasis in Patients with Obesity Over 52 Weeks.
Article in Dermatology and therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03897088 (A Multicenter, Randomized, Double Blind, Placebo Controlled Clinical Study to Assess the Efficacy and Safety of Tildrakizumab in the Treatment of Moderate to Severe Plaque Psoriasis of the Scalp), which is not on this 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.

Abstract
introductionObesity contributes to inflammation and may decrease psoriasis treatment efficacy. We investigated whether obesity affects the efficacy and safety of tildrakizumab, an anti-interleukin-23 p19 antibody approved for the treatment of adults with moderate-to-severe plaque psoriasis, for scalp psoriasis treatment.
methodsThis was a subgroup analysis of a randomized, double-blind, placebo-controlled, Phase 3b trial in patients with moderate-to-severe plaque psoriasis affecting the scalp. Patients receiving tildrakizumab 100 mg or placebo were analyzed by baseline obesity status (body mass index ≥ 30 versus < 30 kg/m
resultsIn the intention-to-treat population, 56/117 (47.9%) patients randomized to tildrakizumab and 57/114 (50.0%) to placebo had obesity (modified intention-to-treat population: tildrakizumab, 43/89 [48.3%]; placebo, 40/82 [48.8%]). At Week 16, significantly more patients treated with tildrakizumab versus those receiving placebo achieved IGA mod 2011 (scalp) (obesity, 21/43 [48.8%] versus 4/40 [10.0%], p = 0.0002; no obesity, 23/46 [50.0%] versus 2/42 [4.8%], p < 0.0001) and PSSI 90 responses (obesity, 27/43 [62.8%] versus 4/40 [10.0%], p < 0.0001; no obesity, 27/46 [58.7%] versus 0/42 [0.0%], p < 0.0001). Treatment effect was also maintained for Scalp Itch-NRS response (p < 0.0001) and mean %CFB in affected SSA (no statistical testing), regardless of obesity status. Results in patients treated with tildrakizumab were similar through Week 52. No new safety signals were identified.
conclusionsNo statistically significant differences in efficacy or safety were observed between patients with and without obesity. CLINICALTRIALS: GOV IDENTIFIER: NCT03897088.
