Gas Chromatography Chemometrics of Volatile Analytes in Mexican Mezcals: Fingerprinting Ancestral and Artisanal Manufacturing Processes, Geographical Origins, and Agave Species.

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
In this study, we developed a chemometrics approach for fingerprinting and identifying discriminant metabolites in Mexican mezcals. The approach was based on direct immersion solid-phase micro-extraction (DI-SPME) and gas chromatography-mass spectrometry (GC-MS). We used multivariate statistical analysis (MSA) to discriminate between ancestral and artisanal manufacturing processes, as well as between different geographical origins and agave species. The designed GC-MS-MSA separation method, labelled "Method 1", enabled the unequivocal identification of twelve marker compounds that were confirmed with Electronic Impact Mass Spectrometry (EI-MS) mass-profile analyses, comprising a pairwise comparison between experimental
