Ancient DNA reveals 4000 years of grapevine diversity, viticulture and clonal propagation in France.

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
Wine production has deep historical roots in France, yet the biological foundations of early viticulture remain elusive. We report genome-wide ancient DNA data from 49 archaeological grape pips spanning ~4000 years, from the Bronze Age to the Medieval period, primarily focusing on France. Population genetic analyses reveal the genetic makeup of wild local grapevines in the Bronze Age and the early use of domesticated grapevines by ~625-500 BCE. Roman-era genomes reflect long-distance exchange from Iberian, Balkan, Levantine, and Caucasian domesticated varieties. Vegetative propagation, evidenced by genetically identical clones across sites and centuries, emerged by the mid-Iron Age and became a pillar of viticultural practice. Remarkably, one Medieval sample from Valenciennes is genetically identical to modern 'Pinot Noir', demonstrating clonal continuity over nearly 600 years. This study traces the introduction, integration and spread of diverse grapevine ancestries that have contributed to shape the varietal landscape of French viticulture.
