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
Total reflection X-ray fluorescence (TXRF) is a well-established method to detect ultra-trace elements present in water as well as in other liquids that can be diluted into the water medium. In the present case study, we have applied the TXRF technique to analyze various elements present in the Maha Kumbh-2025 water sample, which was collected from the nose point of Triveni Sangam, at Prayagraj, India. In addition, we have also performed intercomparative quantitative analysis of other water samples collected from different water resources. Our results show that the concentrations of different elements present in the Maha Kumbh-2025 water samples are well within the acceptable limits defined by the WHO guidelines (for drinking water). Furthermore, we did not observe the presence of any heavy toxic elements (e.g., chromium (Cr), arsenic (As), mercury (Hg), and lead (Pb)) in the Maha Kumbh-2025 water sample within the range of detection limits (DL) of our technique. This case-study-based investigation provides a site-specific insight into the elemental quality of water at a location where a large mass-gathering festival is organized. It clearly demonstrates the practical applicability of TXRF as a rapid and reliable monitoring tool for assessing the quality of water from environmental pollution aspects.
