Pruritus in atopic dermatitis: a cross-sectional study of adult patients from a tertiary university hospital in São Paulo, Brazil.

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
backgroundChronic pruritus is the defining symptom of atopic dermatitis (AD). Although AD is common in Latin America, there is little data regarding pruritus intensity, characteristics, and effects on quality of life in this population.
objectiveThis cross-sectional study aimed to evaluate pruritus in 91 patients with AD at a tertiary university hospital in São Paulo, Brazil. Patients aged 14‒65-years old were included in this study.
methodsPatients completed the Itch Questionnaire, the ItchyQoL, and the POEM questionnaires and were asked to rate their itch severity using a 10-point peak pruritus Numerical Rating Scale (NRS). AD severity was assessed via the EASI and the vIGA-AD.
resultsThe mean age was 29.68 ± 12.87years, and 56.0% of patients were White. 97.8% of patients were currently experiencing pruritus with an average NRS of 7.32 ± 2.22. Patients had associated bleeding (71.4%), heat sensation (63.7%), and pain (54.9%). Worsening factors included stress (93.4%), dry skin (91.2%), and sweat (75.8%). The mean total ItchyQoL score was 78.93 ± 17.20. Female gender was significantly associated with a higher total ItchyQoL score (p = 0.009). Pruritus on the neck, foot, and whole body was associated with higher total ItchyQoL scores in adjusted models (p < 0.05). The EASI, vIGA-AD, and POEM were moderately correlated with itch intensity (r = 0.434, 0.406, and 0.610) and total ItchyQoL score (r = 0.425, 0.436, and 0.631). STUDY LIMITATIONS: The predominantly White population cohort may not be representative of the diverse AD phenotypes in the Brazilian patient population. Children under the age of 14 and adults over the age of 65 were excluded from the population cohort. Furthermore, patients included in the study may suffer from other non-dermatological diseases that cause itch, which may influence the outcomes oberserved.
conclusionsPatients with AD in Brazil experience significant pruritus that impacts their quality of life. Gender, body location of itch, associated pain, and stress should all be taken into consideration when evaluating AD patients with pruritus.
