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.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

This study aimed to assess whether delivering Continuous Positive Airway Pressure (CPAP) through a Helmet interface (H-CPAP) reduces common carotid artery flow (CCAF), compared to breathing room air (RA) or using an oronasal mask (M-CPAP). This trial is an unblinded, randomized, controlled crossover trial. The primary outcome was CCAF, measured using Doppler ultrasound. The secondary outcome was mean arterial pressure (MAP). A convenient sample of adult healthy volunteers was enrolled. Subjects were enrolled and randomized to receive either H-CPAP or M-CPAP first at + 10 cmH
