Adherence to CPAP with a nasal mask combined with mandibular advancement device versus an oronasal mask: a randomized crossover trial.
Trial report in Sleep & breathing = Schlaf & Atmung, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01889472 (Impact of Nasal Mask/Oronasal Mask on Compliance to Treatment With Continuous Positive Airway Pressure), which is not on this map. Cited by 1 paper, 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.

Abstract
purposeEvidence for the management of CPAP-treated obstructive sleep apnea suggests that oronasal masks reduce mouth leaks at the expense of higher pressures and poorer adherence. Some authors have proposed the use of mandibular advancement devices in combination with nasal masks to address this. The aim of this study was to assess adherence to CPAP after 1 month's use of a nasal mask with a mandibular advancement device and to compare adherence with an oronasal mask.
methodsA randomized crossover trial design to assess whether a mandibular advancement device combined with a nasal mask would improve CPAP adherence compared to an oronasal mask.
resultsThere was no improvement in CPAP adherence and self-reported interface-related pain was significantly higher with the combined treatment.
conclusionsAlthough the combined treatment reduced pressures, likely by improving upper airway patency, it may only be appropriate for a small number of patients due to associated discomfort.
