Declining Trends in Gastrointestinal Parasitic Infections Among Nepalese School Children: A Systematic Review and Meta-Analysis (2004-2022).
Article in Public health challenges, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Gastrointestinal parasitic infections (GIPs) remain a major health concern in low-income countries, particularly among school-aged children. Nepal's national deworming program, launched in 2004, has significantly improved in controlling GIPs, yet they persist in many areas. This review synthesizes evidence on the prevalence and temporal trends of GIPs among schoolchildren in Nepal. Methods: PubMed, Google Scholar, and regional databases were searched for studies published between 2004 and 2022, reporting the prevalence of GIPs among children aged 5-17 years. Studies providing information on sample size, location, and clear diagnostic methods were considered eligible for analysis. Pooled prevalence estimates were calculated using a random-effects model (DerSimonian-Laird) with logit transformation. Heterogeneity ( Results: Twenty-five studies comprising 17,628 stool samples were included, of which 7091 (40.2%) tested positive for GIPs. The pooled prevalence was 28.6% (95% CI: 21.7%-36.7%), with substantial heterogeneity. Prevalence declined significantly over time (OR = 0.58, 95% CI: 0.41-0.81), from 43.4% (2004-2010) to 24.2% (2010-2016), followed by a slight increase to 28.4% (2016-2022). Prevalence was similar by sex, with approximately 12.7%, and urban areas had a slightly higher prevalence (29.0%) than did rural areas (27.9%). Helminth infections (20.0%) were more common than protozoans (9.9%), and in 7.7% (95% CI: 5.6%-9.7%) of the children, polyparasitism was recorded. Conclusion: GIPs among Nepalese schoolchildren have declined notably over the past two decades but remain a persistent concern. Continued disparities highlight the need for sustained deworming, sanitation, and region-specific monitoring.
