A Metabolome Atlas of Grape Biodiversity.
Article in Journal of agricultural and food chemistry, 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
Grapevine (Vitis spp.) is one of the world's most economically, culturally, and biologically important fruit crops, with remarkable diversity spanning thousands of V. vinifera cultivars together with rootstocks and wild relatives. Yet grapevine biodiversity has never been systematically explored at the metabolome scale, despite its importance for chemotaxonomy, breeding, and sustainable viticulture. Here, we present the Grape Metabolome (GM) Project, the first systematic liquid chromatography-mass spectrometry (LC-MS) survey of grapevine biodiversity, comprising 462 samples from 126 accessions collected across four vintages. Advanced and well-established chemometric tools resolved the major grape chemotypes together with finer cultivar-related substructure, while annotation-guided interpretation linked this organization to distinctive patterns in anthocyanins, flavonols, aroma-related compounds, and tannin-associated phenolics. This data set provides a reference framework for chemotaxonomy, breeding, authenticity, precision viticulture and enology.
