Distinct comorbidity profiles in atopic versus non-atopic prurigo nodularis: a cross-sectional analysis.
Article in Archives of dermatological research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Prurigo nodularis (PN) is a chronic inflammatory skin condition frequently associated with atopy, yet the relationship between atopic status and comorbidity profiles in PN patients remains poorly understood. Using the 2016-2019 National Inpatient Sample database, we analyzed 7,765 patients with PN to compare epidemiological characteristics and comorbidity patterns between atopic and non-atopic cohorts. Among these patients, 1,545 (19.9%) had concomitant atopy, defined as the presence of at least two atopic conditions (atopic dermatitis, allergic rhinitis, or asthma). Atopic PN patients were more likely to be female, Black, and reside in central metropolitan areas with higher median household incomes. After adjusting for demographic and socioeconomic factors, the atopic cohort showed significantly higher odds of cardiovascular conditions (including atrial fibrillation: aOR 2.84 [1.31-6.40]), gastrointestinal disorders (such as GERD: aOR 1.57 [1.18-1.95]), and neurological conditions (including chronic pain: aOR 2.08 [1.39-3.03]). Conversely, they demonstrated lower odds of renal complications, including acute kidney failure (aOR 0.58 [0.40-0.83]) and end-stage renal disease (aOR 0.62 [0.43-0.90]). These findings suggest clinically distinct subtypes of PN based on atopic status, which could inform risk assessment and guide personalized treatment approaches.
