1 · What the graph read from it

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.

2 · The registry

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

backgroundPsoriasis is a chronic immune-mediated skin condition. Evidence supporting dietary management of psoriasis is limited. However, People Living with Psoriasis (PLwP) trial dietary interventions as a management strategy, often taken from popular literature. Social media is a popular source of nutrition information. However, little is known about the dietary information suggested for psoriasis on these platforms. The aim of this study was to explore the dietary approaches suggested for psoriasis on Instagram and evaluate their quality. METHODOLOGY: Cross-sectional content analysis of Instagram posts providing dietary information for plaque psoriasis management, posted under the 12 most popular psoriasis hashtags. Posts were evaluated for quality using the DISCERN instrument.

resultsOverall, 138 Instagram posts were analysed. The most common type of dietary recommendation was 'exclusion', most frequently of alcohol and dairy. Detox and 'clean eating' were also frequently mentioned, as well as the inclusion of protein, and adherence to a gluten-free diet. The most common content creators were those with those with lived experience of psoriasis (29.7%). None of the posts were created by qualified nutrition professionals and only 6.5% were by healthcare professionals (HCPs). The majority (99%) of posts identified were of 'poor' quality.

conclusionMost dietary information on Instagram for managing psoriasis is poor quality, restrictive, unsubstantiated and shared by non-HCPs. Therefore, PLwP may be subject to dietary misinformation when using Instagram. HCPs should be equipped to counter diet and psoriasis misinformation. Further research is needed to investigate appropriate ways to provide dietary support for PLwP.
