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

purposeREM-related obstructive sleep apnea (OSA) presents a paradox where a low apnea-hypopnea index (AHI) may mask significant disease. We compared polysomnography, comorbidities, and oxygenation metrics across OSA phenotypes to determine if AHI-based severity classifications underestimate the nocturnal hypoxemia in REM-related OSA.

methodsRetrospectively, 378 OSA patients were classified as REM-related (AHI

resultsThe REM-related group had the lowest AHI

conclusionREM-related OSA is a distinct phenotype where a low AHI
