Trial report in Respirology (Carlton, Vic.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04925466 (Comparison of 10cmH2O and Manual Titrated Pressure in Treatment of Obstructive Sleep Apnea), which is not on this map. Cited by 3 papers.

1 · What the graph read from 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.

2 · The registry

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

BACKGROUND AND

objectivesPatient compliance with continuous positive airway pressure (CPAP) is similar using manual-titrated pressure compared to auto-titration, although auto-titration pressures are usually 2-5 cmH

methodsPart 1, 12 healthy subjects and 16 OSA patients were enrolled in the measurement of expiratory reserve volume, diaphragm EMG, and expiratory muscle EMG at different CPAP levels. Breathing difficulty during different CPAP levels was assessed using a customised questionnaire in 35 healthy subjects and 33 OSA patients. Part 2, a two-night randomised crossover double-blind trial using the tolerable highest CPAP (10 cmH

resultsEnd expiratory lung volume increased significantly with increasing CPAP. In general, diaphragm EMG changed little when CPAP ≤ 10 cmH

conclusionsThis study suggests that most patients with moderate to severe OSA can be effectively treated with CPAP at an initial pressure of 10 cmH

trial registrationClinicalTrials.gov identifier: NCT04925466.
