Determination of Copper in Cachaça Samples Preconcentrated on Filter Paper by Portable EDXRF.
Article in ACS omega, 2026. 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
Cachaça is a distilled beverage made from sugar cane and is the most consumed spirit in Brazil. Among the inorganic elements present in this drink, copper stands out due to its potential harm to human health, which necessitates continuous quality control. In this context, the objective of this study was to develop an analytical method for the determination of copper in artisanal cachaça samples using preconcentration on a paper support and detection by portable X-ray fluorescence spectrometry (pXRF). For the analytical measurements, samples were preconcentrated on commercial filter paper using a volume of 120 μL and a temperature of 120 °C. The method was evaluated through figures of merit such as linear range (2 to 10 mg L
