Epidemiology of intestinal parasitic infections among school-aged children in low- and middle-income countries of Africa and Asia: a systematic review and meta-analysis.
Synthesis in Systematic reviews, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 AND
aimsIntestinal parasitic infections (IPIs) remain a significant public health challenge, particularly among school-aged children in low- and middle-income countries (LMICs). This systematic review and meta-analysis aimed to estimate the pooled prevalence of IPIs and identify associated risk factors in Africa and Asia.
methodA systematic search of Medline/PubMed, Embase, Scopus, ScienceDirect, Epistemonikos, and additional searches such as Google and Google Scholar was conducted between January 2019 and April 2024. The review followed the PRISMA guidelines. Data extraction was performed using Microsoft Excel, and meta-analyses were conducted using STATA. Methodological quality was assessed using the Newcastle-Ottawa Scale. A random-effects model was used to estimate the pooled prevalence, while heterogeneity was assessed using the I
results47 studies comprising 20,334 school-aged children were included. The pooled prevalence of at least one intestinal parasitic infection was 39% (95% CI: 33%-45%). Regional analysis showed a higher prevalence in Africa (41%) compared to Asia (35%). Protozoan infections (29%) exceeded those of helminths (19%) and mixed infections (2%). The most common parasites were Blastocystis hominis (16%), Endolimax nana (16%), Entamoeba histolytica (15%), Entamoeba coli (12%), and Ascaris lumbricoides (11%). Infections were primarily single (37%), followed by double (10%), triple (3%), and quadruple (1%). Significant risk factors included school type, socioeconomic status, larger family size, presence of domestic animals, and finger-sucking habits.
conclusionIntestinal parasitic infections remain a significant public health challenge among school-aged children in Africa and Asia. The findings underscore the need for sustained, school-based health programs that integrate regular deworming, hygiene education, and targeted sanitation improvements. Strengthening surveillance and addressing behavioral and environmental risk factors are essential to reducing infection burden and promoting child health.
