Qualitative exploration of the experiences and perceptions of diet in psoriasis management among UK adults.
Article in BMJ open, 2025. 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
objectiveThis study aimed to explore the use, experiences and perceptions of diet in psoriasis management among adults with lived experience in the UK.
designQualitative. Data were analysed thematically using a reflexive thematic approach.
settingOnline discussions with adults living with psoriasis in the UK.
participantsNine adults (two men, seven women) ≥18 years of age, living in the UK, English speaking, with a diagnosis of psoriasis of any severity.
resultsFour key themes were generated: (1) impact of diet, (2) dietary modification, (3) dietary information and (4) dietary support. Overall, the majority (n=8) perceived that diet had an impact on their psoriasis. Most participants (n=7) reported trying restrictive diets including dairy free, gluten free and 'cleanses' to help manage their psoriasis with limited success. A perceived lack of dietary support resulted in participants relying on social media and online forums for dietary information. Participants reported a high cognitive burden due to the lack of reliable nutrition guidance and insufficient dietary support from healthcare professionals (HCPs).
conclusionsParticipants rely on social media and online forums for dietary information, which suggest unsubstantiated restrictive diets that could negatively impact health. Participants felt overwhelmed by dietary recommendations and wanted more relevant dietary support. In the absence of evidence-based dietary information for psoriasis, HCPs need to be able to provide basic dietary support and combat misinformation. Larger studies aimed at understanding how best to support people with psoriasis are needed.
