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
Purpose: The Subsalve helmet continuous positive airway pressure (CPAP) circuit is a low-cost, easy to implement non-invasive ventilation option for treatment of acute respiratory failure. The circuit is simple to set up and operate, and is designed to be used with any commonly available continuous positive airway pressure device. Model Materials and Methods: Simulation of an acute respiratory distress syndrome (ARDS) patient allows optimization of treatment parameters without risk. The boundaries of safe and effective helmet CPAP treatment were measured in the TestChest Results: Moderate CPAP pressure led to significant increases in SpO Conclusion: Our data demonstrate that the Subsalve helmet CPAP circuit, with limited oxygen availability, is an effective treatment strategy for ARDS patients in low-resource settings. Moderate positive end expiratory pressure (PEEP) is recommended to improve blood oxygenation. Subsalve has the potential to conserve critical resources in future epidemics.
