1 · What the graph read from it

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.

2 · The registry

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 and study aims: Nasogastric (NG) tubes are commonly inserted blindly, leading to complications. Existing NG tube placement-assisting systems face safety and cost-effectiveness issues. This study aimed to evaluate a new assisting system using a camera probe inserted into the NG tube to provide real-time visualization. Patients and methods: Thirty patients requiring nasogastric tube placement were prospectively included. The primary objective was to determine the success rate of NG tube placement, while the secondary objectives included assessment of usability and safety of this system. Results: Our findings revealed a high success rate of 96.7%. Median time to complete NG tube placement was 3.8 minutes. No serious complications were observed during the 7-day follow-up period. Operator feedback indicated this system helps facilitate NG tube placement, identify the gastric mucosa and safety landmark, and ease of camera wire removal. However, image visibility received a slightly lower score due to gastrointestinal secretions entering the NG tube through the side hole. To address this, air insufflation was used to enhance visibility in 13 patients. Conclusions: The video-assisted system provides real-time visualization of the gastrointestinal tract during tube insertion and has been shown to enhance the safety and effectiveness of NG tube placement.
