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

Genome-wide association studies (GWAS) have uncovered multiple loci associated with atopic dermatitis (AD), although mechanistic understanding remains limited. Here, we examine a risk variant in the aquaporin 3 (AQP3) promoter and propose a mechanistic link between genotype to altered autophagy, skin barrier integrity, and wound healing in AD. A GWAS involving 1261 AD cases and 4062 controls of Chinese ancestry from the Singapore-Malaysia cohort was performed. Linkage disequilibrium (LD) analysis and cis-eQTL datasets were used to assess regulatory associations. Functional effects of promoter variants were validated using in vitro luciferase assays and ex vivo transcriptomic profiling. In vitro experiments in HaCaT keratinocytes investigated the effect of siRNA-mediated AQP3 knockdown on autophagy, skin barrier integrity, and wound closure. A discovery GWAS identified significant association between AD and SNP rs12555686 (p = 1.67 × 10
