The Association of Psoriasis and Bacterial Infections in Pediatric Patients: A Retrospective Review.
Article in Pediatric dermatology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
BACKGROUND/
objectivesGuttate psoriasis onset and plaque psoriasis flares are associated with streptococcal pharyngitis. Literature regarding the relationship between anogenital bacterial dermatitis and psoriasis in pediatric patients is limited. We aimed to evaluate the clinical characteristics, microbiology, and treatment course of patients with psoriasis/psoriasiform dermatitis and concomitant pharyngeal and/or anogenital bacterial infections.
methodsA multicenter retrospective review of patients ≤ 18 years of age with psoriasis/psoriasiform dermatitis and bacterial infection, defined by positive culture results, was performed. Demographic characteristics, clinical features, microbiology, treatment recommendations, and outcomes were evaluated. Comparisons were made between pharyngeal and anogenital culture groups.
resultsA total of 166 unique patients with psoriasis/psoriasiform dermatitis and suspected pharyngeal and/or anogenital infection were evaluated between 2011 and 2021. Staphylococcus sp. and Streptococcus sp. were isolated in anogenital cultures. Inverse psoriasis was associated with a positive anogenital culture (p = 0.0356). Guttate psoriasis was more common in patients with a positive pharyngeal culture (p < 0.0001). Treatment of a positive bacterial culture did not correlate with the treatment response of psoriasis/psoriasiform dermatitis.
conclusionsInvestigations for anogenital and pharyngeal infections should be considered in pediatric patients presenting with new-onset or worsening psoriasis. A high clinical suspicion should be maintained for anogenital infection in patients with inverse psoriasis, specifically.
