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.

Abstract

backgroundAcute respiratory distress syndrome (ARDS) is the acute hypoxemic respiratory failure that presents with non-cardiogenic pulmonary opacities. Patients receiving non-invasive respiratory support might present with high transpulmonary pressure, pulmonary strain, and pendelluft, which contribute to the development of patient self-inflicted lung injury (P-SILI). Experimental studies have identified that continuous positive airway pressure (CPAP) is successful in attenuating P-SILI effectors compared to high-flow nasal oxygenation (HFNO). However, it remains uncertain whether this attenuation is associated with a reduction in lung injury and improved clinical outcomes.

methodsThis is a multicenter, randomized, open-label, controlled trial. One hundred and twenty non-intubated patients with established ARDS will be randomly assigned to receive non-invasive respiratory support with either CPAP 12 cmH DISCUSSION: This study will assess the potential role of CPAP in attenuating P-SILI effectors and inflicting less biological lung injury compared to HFNO. This physiologic effect may lead to lower rates of tracheal intubation and mortality. This project will provide new knowledge on the respiratory management of non-intubated ARDS patients, a subject where evidence is lacking.
