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

backgroundArginases (encoded by ARG1 and ARG2 genes) might play an important role in asthma pathogenesis through effects on nitrosative stress. Arginase expression is upregulated in asthma and varies with T(H)2 cytokine levels and oxidative stress.

objectiveWe aimed to examine whether variants in these genes are associated with asthma and whether atopy and exposures to smoking and air pollution influence the associations.

methodsAmong non-Hispanic and Hispanic white participants of the Children's Health Study (n = 2946), we characterized variation in each locus (including promoter region) with 6 tag single nucleotide polymorphisms for ARG1 and 10 for ARG2. Asthma was defined by parental report of physician-diagnosed asthma at study entry.

resultsBoth ARG1 and ARG2 genetic loci were significantly associated with asthma (global locus level P = .02 and .04, respectively). Compared with the most common haplotype within each locus, 1 ARG1 haplotype was associated with reduced risk (odds ratio [OR] per haplotype copy, 0.55; 95% CI, 0.36-0.84), and 1 ARG2 haplotype was associated with increased risk (OR per haplotype copy, 1.35; 95% CI, 1.04-1.76) of asthma. The effect of the ARG1 haplotype that was significantly associated with asthma varied by the child's history of atopy and ambient ozone (P(interaction) = .04 and .02, respectively). Among atopic children living in high-ozone communities, those carrying the ARG1 haplotype had reduced asthma risk (OR per haplotype copy, 0.12; 95% CI, 0.04-0.43; P(heterogeneity) across atopy/ozone categories = .008).

conclusionsARG1 and ARG2 loci are associated with childhood asthma. The association between ARG1 variation and asthma might depend on atopy and ambient ozone levels.
