Volcanic glass geochemical fingerprints of the Black Sea tephra layers in the last ~60 kyr.
Article in Scientific data, 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
Tephra layers preserved in marine sedimentary archives constitute key isochronous markers for reconstructing volcanic activity and regional stratigraphic frameworks. Here we present a comprehensive geochemical dataset of volcanic glass from tephra layers identified in sediment core M72/5-25-GC1 recovered from the southwestern Black Sea. The dataset includes major and trace element compositions of volcanic glass shards from 19 tephra layers deposited in the last ~60 kyr, preserved as both visible tephra and cryptotephra horizons. Glass shards were analyzed using electron probe micro-analyzer and sector-field laser ablation inductively coupled plasma mass spectrometry, following rigorous analytical protocols and quality control procedures. The dataset spans a wide compositional range, reflecting inputs from multiple volcanic regions, including the Central Anatolian Volcanic Province, the Aegean arc, and Italian volcanic districts. This dataset provides a robust geochemical framework for tephra fingerprinting and correlation across the Black Sea and surrounding areas, and represents a valuable resource for tephrochronological applications, paleoenvironmental reconstructions, and future comparative or data-driven studies.
