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

Monthly sampling was conducted at a drinking water treatment plant (DWTP) in Southern Louisiana, USA from March 2017 to February 2018 to determine the prevalence and reduction efficiency of pathogenic and indicator viruses. Water samples were collected from the DWTP at three different treatment stages (raw, secondary-treated, and chlorinated drinking water) and subjected to quantification of seven pathogenic viruses and three indicator viruses [pepper mild mottle virus (PMMoV), tobacco mosaic virus (TMV), and crAssphage] based on quantitative polymerase chain reaction. Among the seven pathogenic viruses tested, only Aichi virus 1 (AiV-1) (7/12, 58%) and noroviruses of genogroup II (NoVs-GII) (2/12, 17%) were detected in the raw water samples. CrAssphage had the highest positive ratio at 78% (28/36), and its concentrations were significantly higher than those of the other indicator viruses for all three water types (P < 0.05). The reduction ratios of AiV-1 (0.7 ± 0.5 log
