Wastewater and Clinical Based Epidemiology for Viral Surveillance in the Nile Delta of Egypt.
Article in Current microbiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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 release of inadequately treated wastewater, containing human viruses, into the water environment or agricultural use represent a major problem in public health. In this study, SYBR Green-based real-time polymerase chain (qPCR) was applied to evaluate the prevalence of human polyomavirus (HPyV), papillomavirus (HPV), hepatitis A virus (HAV), and hepatitis E virus (HEV) in urban sewage and among children with acute gastroenteritis. The seasonal distribution in wastewater and viral removal by wastewater treatment process were also evaluated, over the 2 year sampling period. HPyV, HPV, HAV, and HEV were detected in 68%, 39.6% 42.4%, and 33.3% of the raw sewage, respectively, with highest incidence in winter season. In treated sewage samples, HPyV, HPV, HAV, and HEV were detected in 21%, 9.4%, 18.7%, and 0%, respectively. Furthermore, among the 200 diarrheal stool samples, HPyV, HPV, HAV, and HEV were detected in 72.5%, 50%, 13%, and 5%, respectively. HPyV was more prevalent in both environmental and clinical samples. The mean concentration of these viruses in raw sewage, treated sewage, and stool samples was 3.62 × 10
