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

objectiveInterleukin (IL)-17 plays an important role in the pathogenesis of asthma. We investigated the association between single-nucleotide polymorphism (SNP) of IL-17 (rs2275913, IL-17 G-152A) and asthma-related traits. Its effect on IL-17 production was also attractive.

methodsOne hundred and sixty eight childhood asthmatic patients, 144 bronchiolitis patients, and 205 healthy controls were recruited in this study. SNP rs2275913 was genotyped by polymerase chain reaction-restriction fragment length polymorphism. Peripheral blood mononuclear cells (PBMCs) from parts of healthy controls with different genotype were isolated and cultured with phytohaemagglutinin (PHA) for detection of IL-17 in the supernatants.

resultsSNP rs2275913 was associated with asthma (P = 0.03) in genotype frequency test. Children with homozygous A were 2.29 times more likely to have asthma than others (95% confidence interval 1.39-3.78, P = 0.001). The strength of associations was moderately higher by allergy comorbidity. Furthermore, SNP rs2275913 A allele was associated with abnormal lung function and serum total IgE in asthmatics, although the production of IL-17 by PHA-induced PBMC seemed to be not different among individuals with different genotypes. The distribution of SNP rs2275913 in bronchiolitis was marginally statistically different with controls and demonstrated a tendency close to that in asthma. Higher Streptococcus pneumoniae and Moraxella catarrhalis detection rates were shown in bronchiolitis patients with homozygous A allele than those with other genotypes (20.8% vs. 3.7%, P < 0.01 and 20.8% vs. 6.2%, P = 0.03).

conclusionThe preliminary results demonstrate that IL-17 SNP rs2275913 was associated with several asthma-related traits and confers genetic susceptibility to childhood asthma. It may be used to develop markers to assess the risk of asthma, especially in the bronchiolitis population. It may be a potential bridge to connect the bacterial colonization and the onset of asthma.
