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
Jharkhand is a mineral-rich state and there are many possibilities in pisciculture. Fish is the staple food of Jharkhand because of its nutritional values. In the present study, water, sediment, and the most favorite fish species (Labeo rohita, Catla catla, Cirrhinus mrigala, Cyprinus carpio, and Ctenopharyngodon idella) were collected from the lentic reservoirs and analyzed for assessing the ecological and human health risk assessment. The mean concentrations of Cd, Cr, Cu, Pb, and Zn in water samples varied within the ranges of 0.001-0.004 mg/L, 0.02-0.04 mg/L, 0.004-0.007 mg/L, 0.023-0.081 mg/L, and 0.003-0.12 mg/L, respectively. In sediment samples, the metal concentrations were recorded within the following ranges: 109.15-411.48 mg/kg for Zn, 0.79-22.87 mg/kg for Cd, 22.71-34.79 mg/kg for Pb, 93.44-581.38 mg/kg for Cr, and 19.61-129.09 mg/kg for Cu. The average concentrations of metals in fish were observed as follows: 82.98 - 91.81 mg/kg of Zn, 20.91 - 31 mg/kg of Cd, 81.48 - 91.81 mg/kg of Pb, 442.68 - 482.50 mg/kg of Cr, and 35.91 - 68.57 mg/kg of Cu. Ecological health assessment based on sediment indices shows the prevalence of Cd in the lentic ecosystems and their bioaccumulation (biota-sediment accumulation factor > 2) in fish species. Among the four reservoirs, HD is the most contaminated site. Local population, especially, children of Ranchi district, consuming fish species are prone to health risk due to the metal contamination. Conclusively, this study provides valuable data on metal concentrations in fish species, supporting future ecotoxicology research and policymaking for any mineral-rich state.
