A 3D-Printed Transoral Guide Device to Aid Single-Person Fiberoptic Intubation: A Randomized Clinical Trial.
Trial report in Medical science monitor : international medical journal of experimental and clinical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 Fiberoptic bronchoscopy-guided intubation (FOI) is a reliable method for managing difficult airways, typically requiring a 2-operator technique using jaw thrust. This study introduces a novel 3D-printed transoral guiding device (TGD) enabling single-operator FOI without jaw thrust. The aim was to assess the feasibility and effectiveness of TGD compared to a modified oropharyngeal airway (MOA) with assistant-applied jaw thrust. MATERIAL AND METHODS A total of 218 patients undergoing elective orotracheal intubation were randomized into 2 groups: TGD and MOA. After anesthesia induction, Group TGD underwent FOI using the TGD without jaw thrust, while Group MOA used the MOA combined with jaw thrust. Outcome measures included time to successful intubation, first-attempt success rate, number of attempts or device adjustments, and airway visibility (epiglottis and bronchoscope view). RESULTS Successful FOI was achieved in all patients in the TGD group versus 95.4% in the MOA group (P=0.024). The TGD group had significantly shorter times to visualize the vocal cords and tracheal carina (both P<0.001) and to complete intubation (P<0.001). First-attempt success was higher in the TGD group (99.1%) than in the MOA group (67.0%; P<0.001). Fewer attempts and device adjustments were needed in the TGD group. CONCLUSIONS The 3D-printed transoral guiding device (TGD) facilitates faster, more effective single-operator FOI without jaw thrust, offering a promising alternative to traditional 2-operator techniques.
