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

Extensive wildfire profoundly influences Earth system feedback and can drive major ecosystem disturbances, yet its timing and role in the Late Devonian Frasnian-Famennian (F-F) mass extinction remain unclear. To determine whether wildfires were a driver or consequence of contemporaneous oceanic anoxic events (OAEs), we present a high temporal resolution multiproxy record (biomarkers, microfossils, and trace metals) from the Chattanooga Shale in the southeastern United States. Pyrogenic PAHs and inertinite macerals increased after peaks in δ
