Investigation of Sample Preparation Methods of Dietary Supplements for Total Selenium Determination.
Article in ACS omega, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study investigated three sample preparation methods for digestion of dietary supplements prior to selenium (Se) determination by graphite furnace atomic absorption spectrometry (GF AAS), such as conductive heating digestion, microwave-assisted wet digestion (MWAD), and microwave-induced combustion (MIC). In wet digestion methods, variable nitric acid and hydrogen peroxide concentrations were evaluated. For MIC, a diluted nitric acid concentration was also investigated as absorbing solution, while microcrystalline cellulose was employed as a combustion aid. The optimized conditions were: 250 mg of the sample with 5 mol L
