A Unified Method for Triple Oxygen Isotope Analysis of Sulfate, Water, and Organics.
Article in Analytical 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
Triple oxygen isotope analyses of sulfate, water, and organic materials provide vital insights into geochemical processes. Here, we present the fully automated TORCH method (Triple Oxygen isotope analysis using Reduction, Conversion, and High-precision laser spectroscopy), which enables the direct normalization of various materials to the VSMOW-SLAP reference scale using a unified method. The method integrates high-temperature thermal conversion elemental analysis (TC/EA), high-voltage glow discharge CO-to-CO
