Propranolol mitigates sleep apnea-related cardiac responses during CPAP withdrawal: a randomized placebo-controlled cross-over clinical study.
Trial report in Sleep & breathing = Schlaf & Atmung, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03049306 (Propranolol for Sleep Apnea Therapy), which is not on this 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.

Abstract
backgroundObstructive Sleep Apnea (OSA) causes hemodynamic and autonomic changes during sleep that may promote cardiovascular dysfunction. The extent of heart rate acceleration following respiratory events is associated with mortality in OSA patients. Beta blockers may blunt hemodynamic sequelae of OSA but their impact on heart rate, breathing, sleep and vascular function have not been systematically studied.
methodsWe performed a double-blind randomized crossover study of long-acting propranolol long-acting (LA, 80 mg) vs. placebo interceded by a 1-week washout in OSA patients. In these patients, we used a 3-night CPAP withdrawal protocol to temporarily elicit severe untreated OSA. Participants received propranolol or placebo at 6:30 PM and underwent polysomnography followed by morning blood pressure (BP), reactive hyperemia index (RHI) and augmentation index (AIX) assessments. The primary outcome was heart rate. Secondary outcomes heart rate trajectory over time, OSA severity, sleep architecture, BP, RHI and AIX. Outcomes were compared non-parametric paired tests, or mixed effects regression for heart rate trajectory.
results21 participants (51 ± 11 years old, 62% male, BMI 33.8 ± 6.8 kg/m2) completed the study. Propranolol decreased mean overnight heart rate by 3.6 BPM (p < 0.001). Analysis by event phase revealed that propranolol reduced heart rate during stable sleep and blunted heart rate accelerations associated with apneas, hypopneas and arousals. Propranolol also reduced sleep efficiency, stage N2 sleep percentage and morning diastolic BP was reduced by propranolol but OSA severity, systolic BP, RHI or AIX were unchanged.
conclusionPropranolol mitigates markers of OSA-related cardiovascular risk including disordered-breathing-related heart rate accelerations but impaired sleep quality. These findings may have therapeutic application for patients with OSA and inform the interpretation of data from patients with OSA taking BB. Clinical Trial Registration. NCT03049306.
