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

Closed-circuit rebreather (CCR) and helium-based breathing mixtures are widely used in technical diving. This study compared the effects of Heliox and Trimix on pulmonary function and decompression stress during CCR dives. Nineteen divers performed a standardized dive (50 ± 3 msw, 147 ± 10 min) using Heliox (16% O
