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

Contemporary observations indicate that dissolved oxygen concentrations are generally declining as global temperatures rise, which has broad implications for carbon cycling and the habitable ranges of marine animals. Here, we use the foraminiferal iodine redox tracer to evaluate the distributions of oxygen deficient zones (ODZs) and adjacent low oxygen water masses in the oceans during the Miocene Climatic Optimum ('MCO', 14.7-17 million years ago)-the last time that atmospheric CO
