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: To explore the clinical utility of bedside ultrasound for monitoring gastric residual volume in early enteral nutrition among mechanically ventilated patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Methods: A total of 60 patients with AECOPD and undergoing mechanical ventilation were selected from the intensive care unit (ICU) of the Second Hospital of Jiaxing between April 2020 and April 2023. They were randomly assigned to either an ultrasound group or a control group, with each group consisting of 30 cases. In the ultrasound group, gastric residual volume was monitored using bedside ultrasound measurement of gastric antrum area, while in the control group it was monitored using gastric fluid withdrawal method. The monitoring frequency was set at once every 4 hours, and enteral nutrition was dynamically adjusted based on the monitoring results. The operation time of gastric residual volume monitoring, standard rate of enteral nutrition within 48 h, standard time of enteral nutrition, and the incidence of adverse reactions were compared between the two groups. Results: The operation time for gastric residual monitoring and the duration required for enteral nutrition to reach the standard were significantly shorter in the ultrasound group compared to the control group ( Conclusion: The utilization of bedside ultrasound for monitoring gastric residual volume is both convenient and accurate, thereby facilitating early enteral nutrition in patients with AECOPD and mechanical ventilation, while concurrently reducing the occurrence of complications associated with feeding intolerance.
