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

backgroundHidradenitis suppurativa (HS) is a chronic inflammatory skin disorder increasingly recognized as a systemic disease with diverse comorbidities. While several comorbid conditions are well documented, regional differences in prevalence remain unclear.

objectiveThe aim of this study was to evaluate regional variation in major comorbidities among HS patients, including diabetes, hypertension, depression, smoking, thyroid disorders, acne, obesity, psoriasis, and inflammatory bowel disease.

methodsWe performed a meta-analysis of proportions using a generalized linear mixed model with a binomial distribution and logit link to compare the prevalence of HS-associated comorbidities across North America, Europe, and the Middle East/Asia. Analyses were stratified by adult and pediatric populations, with regional N-values incorporated.

resultsSignificant regional differences were observed in metabolic, endocrine, and psychiatric comorbidities. North American patients had higher odds of diabetes compared to Europe (odds ratio [OR] 1.92) and hypertension compared to the Middle East/Asia (OR 2.99). Depression and thyroid disorders were more common in North America (OR 3.46 and 2.32) and Europe (OR 3.19 and 4.01) compared to the Middle East/Asia. Smoking was more prevalent in Europe compared to North America (OR 0.28) and the Middle East/Asia (OR 2.26). Among pediatric patients, anxiety (OR 0.05) and depression (OR 0.16) were more common in North America, while smoking was more frequent outside North America (OR 12.67).

conclusionsRegional variation in comorbidity prevalence likely reflects differences in lifestyle, diet, sociocultural norms, healthcare literacy, and access to care. Recognizing these patterns may support earlier identification, guide preventive efforts, and inform individualized management strategies in HS.
