Comparing the incidence of epistaxis during nasotracheal intubation with Ring-Adair-Elwyn tubes using virtual versus flexible nasal endoscopy in patients undergoing elective oral and maxillofacial surgeries - A randomized clinical trial.

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 and Aims: Nasotracheal intubation is commonly used in maxillofacial surgeries but often causes complications, with epistaxis being the most frequent. Selecting the more patent nostril and appropriate tube size can help reduce bleeding. Flexible nasal endoscopy (FNE) is traditionally used for this assessment but is invasive. Virtual nasal endoscopy (VNE), a non-invasive imaging technique, may offer an alternative. This randomized controlled study aimed to compare the incidence of epistaxis during nasotracheal intubation when guided by VNE vs FNE. Material and Methods: Sixty-four patients were enrolled. Preoperatively, VNE using OsiriX Lite software identified the more patent nostril and endotracheal tube (ETT) size. On surgery day, FNE was performed to assess the same. Patients were randomized into Group V (virtual) or Group E (endoscopy), with nostril side and Ring-Adair-Elwyn (RAE) tube size chosen accordingly. Incidence and severity of epistaxis during laryngoscopy and before throat packing, ease and time of insertion, manipulations, and number of attempts were recorded. Results: The incidence and severity of epistaxis were significantly less in group V than group E at laryngoscopy (18.8% vs 59.4%, Conclusion: Our study showed that the incidence of epistaxis was significantly less in VNE than in FNE-guided intubation.
