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

backgroundHelicobacter pylori infection increases the risk of developing gastric cancer. Early eradication is effective in reducing the risk. An increasing number of Japanese municipalities are implementing school-based H. pylori screening programs. This study examined an administrative initiative targeting junior high school students to reveal the challenges in enhancing child-centered screening efforts. MATERIALS AND

methodsThis study examined a 2019-2021 population-based H. pylori screening program that targeted second-year junior high school students in Yokosuka City, Japan. The program used a two-tiered approach: initial urine antibody testing, followed by urea breath tests for confirmation. Students with confirmed infections received eradication therapy, and the outcomes were monitored through follow-up testing. Data on participation rates, treatment efficacy, side effects, and family infection surveys were analyzed.

resultsBetween 2019 and 2021, 6270 students in Yokosuka City participated in H. pylori screening, with a confirmed infection rate of 1.2%. First-line eradication therapy achieved a 52.9% success rate, which increased to 94.7% after the second-line treatment. Mild side effects, mainly diarrhea, were reported in 27.0% of the first-line and 22.0% of the second-line cases. Family surveys showed that 48.5% of the infected students had H. pylori-positive relatives, underscoring the importance of addressing familial transmission alongside treatment efforts.

conclusionsH. pylori has low prevalence among Japanese junior high school students in an urban area, with modest eradication success. The low participation and dropout rates highlight the need for improved strategies to boost engagement and ensure comprehensive screening and treatment for better program outcomes.
