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
Background: In all acutely ill patients, adequate nutrition is essential to restore physiologic homeostasis and improve outcomes. Whenever feasible, the enteral route is preferred. In various settings, post-pyloric (nasoduodenal (ND) or nasojejunal (NJ)) feeds may be preferred not only to accelerate attainment of goal feeding volumes, but also to limit gastric volumes in order to decrease the potential risk of aspiration. The current study uses point-of-care ultrasound (POCUS) to evaluate gastric volume and content during enteral feedings in pediatric-aged patients receiving mechanical ventilation in the pediatric intensive care unit (ICU). Methods: Gastric POCUS was performed to evaluate gastric contents in pediatric ICU patients, aged 0-18 years, receiving either gastric or post-pyloric enteral feedings at ≥ 50% goal. The patients were endotracheally intubated and receiving mechanical ventilation. Results: The study cohort included 45 patients, 29 receiving nasogastric (NG) feeds and 16 receiving NJ feeds. The majority of patients (81%) receiving post-pyloric feeds had gastric volumes ≤ 0.4 mL/kg and none had volumes ≥ 2 mL/kg while more than half of NG-fed patients (53%) had gastric volumes ≥ 2 mL/kg. Only three of 18 patients (18.8%) receiving NJ feeds had a gastric volume greater than 0.4 mL/kg. When grading the aspiration risk, there was a higher aspiration risk with NG feeds compared to NJ feeds (33/39 versus 0/18, P < 0.001). Conclusion: Gastric volumes and hence the potential aspiration risk is decreased in patients receiving post-pyloric compared to NG feeds.
