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
<p>Introduction: Nasogastric tube feeding is essential for critically ill patients, yet blind insertion risks misplacement and related complications. Electromagnetic guidance enables real-time tracking, potentially enhancing safety and efficiency. This study aimed to compare the safety and effectiveness of nurse-led electromagnetic-guided nasogastric tube insertion with those of physician-performed blind insertion in critically ill patients.
methodsThis multicenter prospective non-inferiority trial was conducted in seven Japanese intensive care units (July 2023-February 2025). Physicians performed blind insertions in the initial phase, followed by nurse training and electromagnetic-guided insertions using the CORTRAK system. The primary outcome was successful gastric placement without special techniques. Secondary outcomes included insertion time, attempts, complications, and tube position.
resultsA total of 283 patients were analyzed (141 electromagnetic-guided, 142 blind). Success rates were similar (63.1% vs. 65.5%; difference -2.4%, 95% confidence interval: -13.5 to 8.8), confirming non-inferiority (Farrington-Manning p = 0.001). Electromagnetic-guided insertions required fewer reinsertions (median 0 vs. 1; p = 0.049) and less time (3.3 vs. 4.5 min; p = 0.03) in unadjusted analyses. No tracheobronchial misplacements occurred (blind: 1.4%). Complication rates were low and comparable.
conclusionNurse-led electromagnetic-guided nasogastric tube insertion appears to be a safe, effective alternative to physician blind insertion, with comparable success and potential efficiency advantages. </p>.
