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.
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
Background: Soil-transmitted helminth (STH) infections are among the most common parasitic infections worldwide but remain underappreciated in certain regions, including Laos PDR. This study aimed to assess the effectiveness of a 1-year health education intervention on improving knowledge and practices related to STH prevention among grades 4 and 5 primary school pupils in Xay District, Udomxay Province, Laos in 2023. Methods: We conducted a health education intervention study and pre-post intervention surveys using a pre-tested and validated questionnaire. A 2-stage sampling approach selected 363 pupils from Bankhat and Namgan primary schools in Xay District. Pupils' knowledge and practices were assessed and compared before and after the intervention using the McNemar test. Statistical significance was determined at Results: The intervention led to a significant improvement in pupils' knowledge and practices regarding STH prevention. The proportion of pupils with good knowledge increased from 38.3% at baseline to 96.4% at endline, while those demonstrating good practices rose from 34.7% to 91.1%. Conclusion and Recommendations: The health education intervention played a critical role in reducing the risk of STH infections among school-aged children. National health policies in Lao PDR should incorporate comprehensive STH prevention strategies, including school-based health education, improved sanitation, and community engagement, to achieve sustainable impacts.
