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

Groundwater is the primary source of domestic and agricultural use in Chinnalapatti Firka, Dindigul district, Tamil Nadu, India. This study assesses the suitability of groundwater for drinking and irrigation. A total of 120 samples were collected and analysed for physicochemical parameters during the pre-monsoon (PRM) and post-monsoon (POM) seasons, and the contaminants were mapped using GIS-based interpolation. The potential of hydrogen, electrical conductivity, total dissolved solids, total hardness, calcium, magnesium, sodium, potassium, chloride, sulphate, bicarbonate, and fluoride exceed the most desirable limit in both seasons. The Piper diagram indicates that the PRM water type is Mixed HCO₃
