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

Several studies investigated the presence of SARS-CoV-2 in water samples and raw urban wastewater collected from urban sewage treatment plants (STPs) during the COVID-19 pandemic and correlated viral load and epidemiological data. However, limited information is available regarding the potential of urban ditches as sampling sites for epidemiological surveillance. This study aimed to detect SARS-CoV-2 RNA in urban ditches and evaluate its correlation with epidemiological data. A total of 168 samples were collected from January 2021 to February 2022 in three urban ditches and two STPs in the metropolitan region of Vitória, Espírito Santo (ES). Physicochemical and microbiological water quality parameters were analyzed, and SARS-CoV-2 RNA was detected using a TaqMan RT-qPCR system. SARS-CoV-2 was detected in 145/168 of the samples, with 87.2% (75/86) found in the urban ditches and 85.3% (70/82) in the STPs. The viral load in the three urban ditches ranged from 1.59 × 10
