Perfluorononanoic Acid (PFNA) Exacerbates Atopic Dermatitis by Inducing Inflammation in Mice.

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
Perfluorononanoic acid (PFNA) is a ubiquitous persistent environmental pollutant, and several studies have found significant links between atopic dermatitis (AD) and prenatal exposure to PFNA. However, the relationship between PFNA and AD remains unclear. In this study, 2,4-dinitrochlorobenzene (DNCB)-treated female BALB/c mice were used as AD models to investigate the effects of PFNA and its potential mechanisms. These mice were topically applied with 5 mg/kg PFNA per day for 15 days. The results demonstrated that PFNA significantly increased AD lesion severity and clinical symptoms, including dermatitis score, ear thickness, and epidermal thickness. In addition, PFNA also increased the serum IgE level, splenic atrophy, and upregulated the expression of
