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.
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 contamination and seasonal quality variations pose significant challenges in crystalline terrains where rock-water interactions control hydrogeochemical evolution. Despite increasing demographic and agricultural pressures, the Valliyur region in Southern Tamil Nadu lacks comprehensive seasonal hydrogeochemical characterization. This study aims to characterize seasonal hydrogeochemical evolution, assess drinking and irrigation water suitability using comprehensive indices, and identify controlling processes for sustainable groundwater management. The groundwater showed alkaline nature (pH 7.14-8.35) with electrical conductivity (206-11283 µS/cm) and total dissolved solids (96-7334 mg/L) exceeding WHO guidelines in 32% of samples. Total hardness exceeded standards in 48.33% (pre-monsoon) and 43.33% (post-monsoon) samples. ANOVA statistical analysis confirmed that only potassium showed statistically significant seasonal variations (p < 0.001), while geological processes dominated other parameters. The rock-water interactions and weathering process controlled the groundwater geochemistry. The Piper trilinear diagram reveals water types dominated by Ca
