Supine sleep position and angina frequency: an analysis from the sleep heart health study.
Article in Sleep & breathing = Schlaf & Atmung, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeHabitual sleep positions might influence cardiovascular function, but its association with cardiovascular risk in the general population remains unknown. This study aimed to examine the relationship between the supine sleep position and the frequency of angina pectoris (angina), a common symptom of ischemic heart disease, and to explore whether body mass index (BMI) or sex moderate this relationship.
methodsData from the Sleep Heart Health Study (SHHS) were used. Supine sleep position was quantified as the percentage of total sleep duration spent in the supine position, measured by unattended home polysomnography (PSG) during the first SHHS visit. Angina frequency was defined by the number of episodes over a 15-year follow-up period. Multiple Poisson regression was conducted, adjusting for various conventional cardiovascular disease (CVD) risk factors.
resultsThe study included 5,804 participants (52% female), with a mean age of 63 years and an average BMI of 28.16 kg/m
conclusionSleeping in the supine position was significantly associated with more angina episodes. The study lacked information on other sleep positions. Identifying optimal sleep positions to support cardiovascular health could significantly contribute to CVD prevention.
