1 · What the graph read from it

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.

2 · The registry

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

The cycling of volatiles through subduction zones fundamentally shapes Earth's chemical evolution, yet how fluorine (F) and chlorine (Cl) are processed in the deep mantle remains enigmatic. Here, we use high-pressure experiments (5 to 11 gigapascals and 850° to 1200°C) on altered oceanic crust analogs to track deep halogen behavior. We show that phengite remains stable to 11 gigapascals and 1050°C, efficiently transporting F and Cl to ~330-kilometer depth. Upon breakdown or melting, phengite strongly fractionates these halogens: Cl is released into fluids or melts, while F is sequestered in residual phases such as KMgF
