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

Most of the global populace is susceptible to Helicobacter pylori (H. pylori) infection, which typically manifests in childhood. This study aimed to identify the role of TLR9 (rs352140) gene in suppressing or promoting the inflammation related to H. pylori infection in children. This cross-sectional study enrolled 100 children with dyspeptic symptoms undergoing upper endoscopy, including 50 with confirmed H. pylori infection and 50 age- and sex-matched H. pylori-negative controls. All children undertook full history, complete clinical investigation, laboratory testing, upper digestive endoscopies and genotyping of TLR9 (rs352140). A statistically significant difference presented among H. pylori positive and H. pylori negative children as regards TLR rs352140 gene polymorphism, as patients have statistically higher frequencies of homozygous TT genotype, CT genotype and of variant T allele in contrast to H. pylori negative group. Hazard of H. pylori is 7.9 times higher in children with TT genotype and 3.6 times higher in children with CT genotype in contrast to children carrying CC genotype. Also, children carrying the altered T allele had a statistically higher risk of H. pylori, 2.3 times in contrast to those carrying C allele. TLR9 rs352140 gene polymorphism was correlated with of H. pylori infection and incidence of gastritis in children.
