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

backgroundIn 2007 the International Psoriasis Council considered palmoplantar pustulosis (PPP) a condition separate from psoriasis, and several authors maintain that PPP is a reactive process to metal contact allergies independent from psoriasis.

objectivesTo evaluate the frequency of allergies and psoriasis in patients with PPP and to determine the role of allergens in PPP.

methodsA systematic search of the English databases (PubMed and Web of Science) from January 1964 to August 2018 to identify all patients affected by PPP and allergies and/or psoriasis.

resultsIn total, 16 publications describing a total of 519 patients with PPP were evaluated and 122 cases of concomitant PPP and metal allergy were found. The frequency of allergies among patients with PPP was 22.7%; between the identified allergens, 84.3% of cases correspond to metal allergies. In 65.1% of metal allergies, an improvement in PPP was seen after withdrawal of contact. The concomitant presence of psoriasis was recorded in 18% of the cases.

conclusionThere is some evidence to support the association of PPP with metal allergies but also with psoriasis, suggesting the role of metal allergens as a trigger factor in patients with PPP.
