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

AIMS/

introductionObstructive sleep apnea (OSA) is a multifaceted condition that may variably influence metabolic risk. This study aimed to identify physiological phenotypes of OSA using polysomnographic (PSG) data and examine their association with type 2 diabetes (T2DM) in a Japanese cohort. MATERIALS AND

methodsAmong 3,683 individuals who underwent attended PSG between April 2019 and March 2024, 602 adults with OSA were included. Phenotypes were identified by k-means clustering. The association between phenotype and T2DM was assessed using logistic regression adjusted for covariates.

resultsFive phenotypes were identified: Severe desaturation, REM-predominant, PLMS-dominant, Sleep-fragmented, and Mild. Severe desaturation and REM-predominant types showed higher T2DM prevalence (54.5% and 45.7%). In multivariable analysis, both were independently associated with T2DM compared with the Mild type (adjusted odds ratio [OR] 5.00, 95% CI 1.52-16.4; and OR 3.12, 95% CI 1.32-7.38). To further explore the underlying mechanisms, logistic regression including all participants showed that CT90 was independently associated with T2DM, even after adjustment for arousal threshold and AHI.

conclusionsData-driven clustering identified distinct physiological phenotypes of OSA. In addition to the Severe desaturation type, the REM-predominant type was also strongly associated with T2DM, underscoring the metabolic heterogeneity of OSA. Prospective studies are needed to determine causal relationships and evaluate phenotype-targeted interventions.
