Obstructive sleep apnea during rapid eye movement sleep in patients after percutaneous coronary intervention: a multicenter study.

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.
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
purposeObstructive sleep apnea (OSA) during the rapid eye movement (REM) stage of the sleep cycle is associated with intense hypoxemia and cardiovascular instability. We characterized OSA during REM sleep in patients after percutaneous coronary intervention.
methodsIn this multicenter study, 204 patients who had undergone percutaneous coronary intervention in the prior 6 to 36 months were recruited for in-laboratory polysomnography. The primary measure was respiratory events during REM sleep. The patients were divided into 2 groups: (1) OSA during REM sleep (≥ 15 events/h) and (2) absence of OSA during REM sleep (< 15 events/h).
resultsBased on the overall apnea-hypopnea index ≥ 15, 148 patients (74.0%) had OSA. After excluding patients with failed polysomnography or REM sleep < 30 min, 163 patients formed the cohort for this analysis. OSA during REM sleep was diagnosed in 132 patients (81%). Compared with the patients without OSA during REM sleep, those with OSA during REM sleep had a higher body mass index (p = 0.003) and systolic blood pressure (p = 0.041), and a higher prevalence of diabetes mellitus (p = 0.029). Logistic regression analysis, including age, sex, diabetes mellitus, indication for percutaneous coronary intervention, and indication for multi-vessel percutaneous coronary intervention, showed that diabetes mellitus was the only independent predictor of OSA during REM sleep (odds ratio 2.83; 95% CI, 1.17 to 6.83; p = 0.021).
conclusionIn patients treated with percutaneous coronary intervention, there was a high prevalence of OSA during REM sleep. Diabetes mellitus was an independent predictor of OSA during REM sleep.
