1 · What the graph read from 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.

2 · The registry

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

Hepatitis E virus (HEV) represents an important public health concern in many developing countries, including Africa. Transmission of HEV to humans by contaminated drinking water is the most important mode of transmission in low- and middle-income countries. This study aimed to assess the presence of HEV in the environment in Cameroon through molecular analysis of sewage samples. Retrospectively, a total of 157 sewage samples collected between January 2018 and December 2019 were randomly selected and analyzed by molecular techniques to detect and characterize the HEV followed by sequencing and phylogenetic analysis. Three samples (1.9%) collected from North, Far North, and Adamawa regions were positive by real-time reverse transcription polymerization chain reaction. Among these, 2 samples were positive for HEV ribonucleic acid by nested reverse transcription polymerization chain reaction and only one yielded a good sequencing product. Phylogenetic analysis of this unique HEV strain showed that this HEV strain belonged to genotype 3, subtype 3a, and clustered with swine HEV strains from Cameroon, Argentina, and the USA. This study provides preliminary data on the circulation of HEV in wastewater in Cameroon. Further studies will be needed to assess the overall situation in Cameroon.
