The triple threat of Cryptosporidium, Giardia, and Entamoeba infections in Nigerian children.

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
The epidemiological patterns and risk factors of three protozoan parasites, Cryptosporidium, Giardia, and Entamoeba, that cause diarrheal diseases in low-resource settings were investigated among children aged 10 years and below across ten states in Nigeria. Previous studies in Nigeria relied primarily on microscopy, a method with limited sensitivity for parasite detection, which underestimated the true burden of infection. We applied a real-time PCR technique on DNA extracted from 977 stool samples collected from children who answered a structured questionnaire in this cross-sectional survey. The overall prevalence of Cryptosporidium, Giardia, and Entamoeba infections was 18.1%, 77.6%, and 12.3%, respectively. Coinfections were frequent, with 17.1% harbouring both Cryptosporidium and Giardia, 2.9% with Cryptosporidium and Entamoeba, 11.5% with Giardia and Entamoeba, and 2.8% with all three parasites. Jigawa State recorded the highest burden of coinfections (7.9%). Cryptosporidum infection rates were significantly higher in children five years and above, while males had higher Entamoeba infection rates. Giardia infection varied significantly with educational level. Trading was significantly associated with the burden of single infections and Cryptosporidium and Giardia, and Giardia and Entamoeba coinfections. Risk factors for infection and coinfection included geographical location, water source, household density, and contact with animals. The study highlights the importance of integrating molecular diagnostic tools into public health surveillance to accurately assess parasitic disease burdens and guide interventions. The high prevalence of Giardia, in particular, underscores the urgent need to improve access to clean water, sanitation, and hygiene (WASH) infrastructure in Nigeria. Addressing these infections through improved diagnostics, sanitation infrastructure, and targeted interventions could substantially reduce childhood morbidity and mortality associated with diarrheal diseases.
