Effect of continuous positive airway pressure on blood pressure in normotensive individuals with obstructive sleep apnoea: a randomised trial.
Trial report in The European respiratory journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundThe effects of continuous positive airway pressure (CPAP) on blood pressure (BP) in normotensive subjects, particularly among those with a dipping BP pattern, remain uncertain, raising questions about its indication for this group of patients. We assessed the impact of CPAP on BP in normotensive subjects with a dipping BP pattern and severe obstructive sleep apnoea (OSA).
methodsThis was a randomised, parallel, prospective, controlled trial. Inclusion criteria were: age ≥18 years, apnoea-hypopnoea index ≥30 events·h
resultsThe 60 patients who completed the follow-up had a mean±sd age of 52.2±10.8 years and 40 (66.7%) were male. The intention-to-treat analysis showed no significant changes with CPAP, whereas the usual care group experienced increases in ABPM parameters. This resulted in a mean difference of -3.4 mmHg (95% CI -6.124- -0.676; p=0.015) in night-time diastolic BP between the groups. The per-protocol analysis indicated significant differences between the CPAP and usual care groups for all primary end-points, except for daytime systolic BP. For night-time systolic BP, the mean difference was -6.052 mmHg (95% CI -10.895- -1.208; p=0.016).
conclusionThese findings suggest a protective effect of CPAP, highlighting the importance of CPAP prescription for this population to control potential increases in BP and possibly prevent the onset of hypertension.
