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

The proliferation of unconventional oil and gas development over the last two decades has raised concerns about impacts to surface and ground waters. Contamination associated with hydraulic fracturing introduces hydrocarbons and other harmful pollutants to drinking water sources. In this study, we evaluated the impact of a well communication event (frac-out) that occurred on June 19, 2022, in New Freeport, Pennsylvania. Over two years, 75 residential well and surface water samples were collected from surrounding areas and analyzed for anions, cations, and light hydrocarbons. Each sample was then assigned a Multi-component Contamination Index (MCI) (on a scale of 0-6) based on mass ratio space analysis (Ca/Sr, Br/SO
