NSAID Tolerance Can Be Restored in NECD Even in the Absence of Complete Remission of Urticaria.
Article in Clinical and translational allergy, 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/
aimData on the course of nonsteroidal anti-inflammatory drug (NSAID) hypersensitivity in NSAID-exacerbated cutaneous disease (NECD) are limited. We aimed to evaluate NSAID tolerance in NECD patients with well-controlled urticaria.
methods142 patients with well-controlled urticaria [Urticaria Control Test (UCT) ≥ 12; Urticaria Activity Score over 7 days (UAS7) ≤ 6] underwent a single blind, placebo-controlled acetylsalicylic acid (ASA) provocation test. Patients were categorized into three groups based on their treatment; omalizumab, antihistamine, or no treatment.
resultsThe median age of the patients was 40 years (IQR 31.5-52), and 79.6% were female. The median disease duration of chronic spontaneous urticaria (CSU) was 4 years (IQR 2-8). The ASA provocation test was positive in 29 patients (20.4%). Positive patients had lower UCT and higher UAS7 scores (both p < 0.001). ASA provocation test positivity was more common in the antihistamine group compared to both the omalizumab (p = 0.001) and untreated groups (p < 0.001). ROC analysis showed that UCT ≤ 15 predicted ASA provocation test positivity with 72.4% sensitivity and 83.2% specificity, while UAS7 ≥ 4 predicted positivity with 72.4% sensitivity and 86.7% specificity. The negative predictive values (NPV) were 92.2% and 92.5%, respectively.
conclusionTo our knowledge, this is the first study to demonstrate, in a large NECD cohort, that NSAID tolerance can be achieved in patients with well-controlled urticaria under different treatment modalities, regardless of complete remission status. UCT ≤ 15 and UAS7 ≥ 4 are useful clinical predictors of provocation test positivity and, given their high NPVs, are particularly valuable for excluding positivity.
