Global prevalence and public health impact of intestinal parasitic infections in children under five: a systematic review and meta-analysis.

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
backgroundIntestinal parasitic infections (IPIs) remain a significant public health concern worldwide, particularly affecting children under five years old. These infections contribute to malnutrition, impaired growth, diarrhea, and increased morbidity and mortality, disproportionately impacting low- and middle-income countries. This systematic review and meta-analysis aims to estimate the global prevalence of IPIs in children under five and examine the influence of socioeconomic, environmental, and diagnostic factors.
methodsA systematic literature search was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines across multiple databases (PubMed, Web of Science, Scopus, ScienceDirect, and Google Scholar) for cross-sectional studies reporting the prevalence of IPIs in children under five years old, up to November 2025. The pooled prevalence was estimated using a random-effects meta-analysis, and subgroup analyses were performed by region, human development index (HDI), income level, climate, diagnostic method, and parasite species. Methodological quality was assessed using an adapted Newcastle-Ottawa Scale.
resultsForty-one studies, involving a total of 15,109 children under five, met the inclusion criteria. The study population was drawn from multiple regions worldwide. The overall pooled prevalence of IPIs in children under five was 31.60% (95% CI: 26.04-37.44). Prevalence was highest in lower-middle-income countries (37.45%) and low-HDI regions (35.17%), and lowest in high-income countries (6.25%) and very high-HDI regions (19.41%). South Asia (35.47%) and Eastern sub-Saharan Africa (35.24%) were identified as major hotspots. Helminth infections were most commonly caused by Ascaris lumbricoides (11.93%), while Giardia lamblia (10.37%) was the predominant protozoan. Studies using more sensitive diagnostic methods reported substantially higher prevalence. Environmental factors such as tropical savanna climates, moderate rainfall, and high humidity were associated with increased infection rates. Gender differences in prevalence were negligible.
conclusionsIPIs continue to pose a substantial global health burden on children under five, with socioeconomic and environmental disparities strongly influencing prevalence. The findings highlight the need for targeted public health interventions, including deworming programs, improved sanitation, and clinical surveillance, particularly in high-burden regions. Enhanced diagnostic strategies are essential to accurately capture infection rates and guide effective prevention and treatment efforts.
