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
Introduction Accurate imaging of nasal bone fractures is essential for proper diagnosis and management. Traditional methods such as lateral cephalograms and standard radiographs often suffer from limitations in resolution and positioning accuracy. This study introduces and evaluates a novel radiographic technique, that is, NASO-RVG (NR), utilizing radiovisiography (RVG) in combination with a portable X-ray unit for the improved visualization of nasal bone structures. Objective This study aimed to assess the efficacy and diagnostic clarity of the NR technique in nasal bone imaging when compared with conventional lateral cephalometric radiography. Methods A pilot study was conducted on 20 patients presenting with nasal bone fractures. Group A (n=10) underwent radiographic assessment using the NR technique, while Group B (n=10) received standard lateral cephalogram imaging. Parameters evaluated included image clarity, anatomical detail, ease of positioning, and diagnostic confidence, rated by blinded radiologists using a standardized scoring system. Results The NR technique demonstrated significantly improved visualization of fracture lines, better delineation of nasal bone contours, and higher diagnostic confidence scores (p<0.05) compared to the conventional lateral cephalogram. Additionally, patient positioning was easier and more reproducible with the NR technique. Conclusion The NR technique offers a reliable, high-resolution, and portable alternative for nasal bone imaging, with potential benefits in both emergency and outpatient settings. Further large-scale studies are recommended to validate these findings and establish clinical protocols.
