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

introductionHand eczema, skin barrier function and skin microbial contamination among waste workers are underexplored. This study aims to assess: (1) the prevalence and risk factors of hand eczema, (2) the levels of transepidermal water loss (TEWL), and (3) skin microbial contamination in waste sorting workers.

methodsUsing the Nordic Occupational Skin Questionnaire-2002, data were collected from 69 waste sorting workers and 25 office personnel. TEWL was measured with a Tewameter (TM 300, Courage+ Khazaka Electronic, Köln). Microbial skin samples were collected from the left dorsal hand with sterile swabs (Copan, Italy) and cultured. Analyses included descriptive statistics and multivariate logistic regression.

resultsThe hand eczema prevalence was 25% among waste workers and 40% in office personnel. The prevalence of hand eczema was significantly lower among exposed workers compared to controls (p = 0.012). TEWL and fungal concentrations were comparable across groups. Atopic dermatitis (AD) and nicotine use were significant predictors of HE. The prevalence of hand eczema experienced during the past week was significantly associated with elevated bacterial concentrations (p value = 0.05) in both groups.

conclusionsWaste sorting workers had up to 2.4 times higher prevalence of hand eczema compared with the general population, but a lower prevalence than office workers in the same industry. These findings may reflect a potential healthy worker effect. The potential role of bacterial concentrations in the occurrence of hand eczema warrants further investigation.
