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
Objective: The objective of this study was to evaluate the effectiveness of diaphragmatic ultrasonography in conjunction with intra-abdominal pressure (IAP) measurement for assessing diaphragm function and determining the optimal timing for weaning from mechanical ventilation (MV). Methods: A cohort of 100 patients undergoing MV at the intensive care department of the Affiliated Hospital of Hebei University between January 2023 and July 2023 was enrolled. Spontaneous breathing trials (SBTs) were performed once patients met the weaning criteria. At the 30-minute mark of the SBT, diaphragmatic ultrasonography and IAP measurements were conducted. Based on weaning outcomes, patients were categorized into successful and failed weaning groups. Diaphragmatic excursion (DE), diaphragm thickening fraction (TFdi), diaphragmatic rapid shallow breathing index (D-RSBI), and IAP were compared between groups. The predictive value of these parameters in determining optimal weaning timing was analyzed using receiver operator characteristic (ROC) curves. Results: Compared to the failed weaning group, the successful weaning group exhibited significantly lower values of D-RSBI and IAP values along with higher values of DE, TFdi, diaphragm thickness at end-inhalation (DTei), and diaphragm thickness at end-exhalation (DTee) ( Conclusion: The integration of diaphragmatic ultrasonography with IAP measurement is an effective approach for predicting weaning outcomes in patients undergoing MV. This combined assessment may assist clinicians in optimizing weaning strategies and improving patient outcomes.
