Factors influencing weaning success from mechanical ventilation in Emergency department patients with acute respiratory failure.

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
objectivesTo identify the clinical and physiological factors associated with successful weaning from mechanical ventilation (MV) in patients with acute respiratory failure (ARF) treated in the Emergency department, and to evaluate their short-term prognosis.
methodsThis retrospective study analyzed data from 248 ARF patients who underwent MV in the Emergency department from July 2021 to June 2024. Patients were categorized into weaning success and failure groups based on their ability to maintain spontaneous breathing for over 48 hours post-extubation. Collected variables included demographic characteristics, body mass index, MV duration, Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, blood gas parameters, and diaphragm function metrics. Multivariate logistic regression was used to identify independent predictors of weaning success.
resultsAmong the 248 patients, 165 (66.5%) were successfully weaned. Independent predictors of successful weaning included shorter MV duration, lower APACHE II scores, higher tidal volumes, and lower respiratory rates during spontaneous breathing trials. Diaphragmatic excursion was negatively associated with weaning failure, as was arterial oxygen partial pressure (PaO
conclusionWeaning success in ARF patients managed in the Emergency department is influenced by a combination of clinical severity, ventilatory parameters, and diaphragm function. Recognition of these factors may aid in optimizing weaning strategies and improving patient prognosis.
