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

backgroundNeglected tropical diseases (NTDs) are responsible for substantial illness and death worldwide. Helminthic infections among school-aged children pose a serious public health challenge due to their detrimental effects on health and development.

methodsA wide-ranging search conducted across five databases, including Scopus, EMBASE, PubMed, Web of Science, and Google Scholar to retrieve papers published between 1998 and 2024. To evaluate the combined prevalence, a random-effects model with a 95% confidence interval (CI) was applied, and the statistical analysis was performed using meta-analysis packages in R version (3.6.1).

resultsThere were 190 eligible studies documented in 42 countries, and 199,988 schoolchildren included in this review. The global prevalence of helminthic parasites was 20.6% (17.2- 24.3%). Among the countries studied, Tanzania and Vietnam showed the highest levels of prevalence at 67.41% and 65.04%, respectively, with Toxocara spp. and Ascaris lumbricoides being the most prevalent helminthic parasites at 10.36% and 9.47%, respectively.

conclusionIn conclusion, this study underscores the pressing public health concern of helminthic infections among schoolchildren, largely driven by inadequate sanitation and poor water quality. Prompt action, such as improving sanitation, expanding school-based deworming programs, and enhancing access to safe water, is crucial to control these infections and enhance overall health outcomes.
