Mandibular advancement device versus CPAP in lowering 24-hour blood pressure in patients with obstructive sleep apnoea and hypertension: the CRESCENT trial protocol.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04119999 (A Cardiosleep Research Program on Obstructive Sleep Apnea, Blood Pressure Control and Maladaptive Myocardial Remodeling), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
introductionAlthough treatment of obstructive sleep apnoea (OSA) using continuous positive airway pressure (CPAP) reduces blood pressure (BP), adherence to CPAP is often suboptimal. A mandibular advancement device (MAD) is a guideline-endorsed alternative therapy for OSA. Still, there is limited evidence on the relative efficacy between MAD and CPAP on BP reduction. We evaluate whether treatment of moderate-to-severe OSA using MAD can improve BP and other health-related outcomes compared with CPAP. METHODS AND ANALYSIS: This is a randomised, controlled, non-inferiority trial conducted. We will recruit 220 Asians with a history of hypertension and high cardiovascular risk for an overnight polysomnography screening. Those with moderate-to-severe OSA (apnoea-hypopnoea index ≥15 events/hour) will be randomised to treatment with either MAD or CPAP in a 1:1 ratio. Stratified by age (60 vs <60 years old), body mass index (25 vs <25 kg/m ETHICS AND DISSEMINATION: The Domain Specific Review Board-C, National Healthcare Group under approved the study protocol (NHG DSRB Ref: 2019/00359, approved on 28 August 2019). Study findings will be disseminated to various local, national, and international audiences through abstract presentations and publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT04119999.
