Characterization and Variability Analysis of Volatile Metabolites From Acer saccharum Leaves From Québec Region.
Article in Chemistry & biodiversity, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Volatile secondary metabolites in plants can serve as valuable biomarkers for the plant's health, stress response, and pest or disease detection. We have investigated the volatilome of Acer saccharum (sugar maple) leaves using two complementary extraction techniques: headspace-solid phase micro-extraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and hydrodistillation followed by gas chromatography with flame ionization and mass spectrometry detection. HS-SPME-GC-MS revealed variability in green leaf volatiles and terpenoids associated with tree diameter and maturity level, with (E)-hex-2-enal and (Z)-hex-3-enyl acetate as the major compounds. The abundance of certain compounds in HS-SPME-GC-MS spectra correlates closely with the tree diameter and is notably different between harvesting sites. Hydrodistillation allowed us to observe and identify 147 volatile compounds and a broad range of metabolites, including fatty acid derivatives and monoterpenoids, but demonstrated low extraction yields. Correlations between volatile profiles and tree traits suggest such compounds may serve as health and stress biomarkers. Our results suggest that volatile compound analysis may be useful for monitoring sugar maple health and provide a foundation for developing in vivo diagnostic tools to detect afflictions before physical symptoms arise.
