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

objectiveChildhood infectious diseases are one of the most known environmental pathogenic causes of childhood asthma. The high prevalence of both Helicobacter pylori infection and asthma in our country prompted us to assess anyprobable association between them in childhood.

methodsThis cross-sectional study recruited 196 children aged 6 to 12 years old comprising 98 asthmatic (case group) and 98 healthy (control group) individuals. Urea breath test was performed for all of the children and H. pylori infection was compared between the two groups according to the urea breath test results.

resultsUrea breath test was positive in 18 asthmatic (18.36) and 23 (23.36) healthy subjects but was not significantly different between the case and controls (p = 0.380). Further analysis in the asthmatic group revealed association of H. pylori infection withage (p < 0.001) and duration of asthma (p = 0.010). However, no significant correlation was found between sex, severity of asthma, controled asthma or abnormal pulmonary function tests with H. pylori infection (p= 0.804, 0.512, 0.854 and 0.292, respectively).

conclusionGiven the results of the study, H. pylori infection was not significantly different between asthmatic and healthy children. In asthmatic patients, there was no significant association between H. pylori infection and sex, severity of disease, control status of disease and normal or abnormal pulmonary function tests. H. Pylori infection had a significant association with increasing age and duration of asthma.
