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

backgroundMechanical power (MP) integrates tidal volume, airway pressures, flow, and respiratory rate into a single estimate of ventilatory energy delivery and serves as an integrative physiologic marker of ventilator-induced lung injury. Lung ultrasound score (LUS) is a bedside tool that quantifies lung aeration loss, reflecting the structural expression of lung injury in acute respiratory distress syndrome (ARDS). However, data correlating MP with LUS and clinically relevant outcomes in ARDS remain limited.

aimTo explore whether MP is associated with lung ultrasound-derived aeration loss and clinical outcomes in moderate-to-severe ARDS.

methodsThis prospective observational study enrolled adult patients with moderate-to-severe ARDS requiring invasive mechanical ventilation for more than 48 hours. MP and LUS were assessed at 0, 24, 48, and 72 hours. Their association was evaluated using Pearson correlation analysis. Associations between MP and 28-day mortality and weaning outcomes were analyzed using logistic regression and receiver operating characteristic curve analysis. Mean MP was defined as the arithmetic mean across the four time points.

resultsForty-four patients were included. MP was strongly correlated with LUS at baseline (

conclusionMP parallels lung ultrasound-derived aeration loss in ARDS and demonstrates associations with mortality and adverse weaning, supporting its potential role as an integrative physiologic marker in individualized ventilatory management.
