Value of diaphragmatic ultrasound parameters in assessing weaning outcomes and survival in ventilator-dependent intensive care unit patients.

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
objectiveTo retrospectively evaluate the utility of diaphragmatic ultrasound parameters in assessing ventilator weaning outcomes and survival in ventilator-dependent intensive care unit (ICU) patients.
methodsA total of 105 ventilator-dependent ICU patients admitted to our hospital between October 2019 and February 2024 were included in this study. Depending on weaning outcomes, patients were divided into a successful group (n = 86) and a failure group (n = 19). Diaphragmatic ultrasound parameters, including diaphragm excursion (DE), diaphragmatic thickness at the end of expiration (DTee), diaphragmatic thickness at the end of inspiration (DTei), and diaphragmatic thickening fraction (DTF), were collected. Receiver operating characteristic (ROC) curves were plotted to assess the predictive value of these parameters for weaning success. Survival curves were analyzed to explore their relationships with survival. Logistic regression analysis was used to identify risk factors influencing survival in ventilator-dependent ICU patients.
resultsDiaphragmatic ultrasound parameters were statistically higher in the successful group compared to the failure group. TFor ventilator-dependent ICU patients, the areas under the curve (AUCs) of DE, DTee, DTei, and DTF in predicting weaning outcomes were 0.757, 0.765, 0.770, and 0.677, respectively. However, when these four indicators were combined for prediction, the AUC could be elevated to 0.938. Logistic regression analysis identified that gender, age, body mass index, disease type, comorbidities, as well as DE, DTee, DTei, and DTF, were not risk factors influencing the survival of these ventilator-dependent ICU patients.
conclusionsDiaphragmatic ultrasound parameters are valuable tools for assessing the weaning outcomes and survival of ventilator-dependent ICU patients. These parameters provide auxiliary guidance for clinical decision-making and subsequent patient management.
