Laryngeal Dimensions: A Computed Tomography Study.
Article in International archives of otorhinolaryngology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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: The computed tomography (CT) details of the dimensions of the larynx are not fully covered in the literature, so it is important to build up a database for the CT measurements of that area in different ethnic groups. Preoperative details provided by CT are crucial prior to any procedure or approach involving the larynx. Objective: To measure and report the different dimensions of the larynx and vocal cords through CT. Methods: We analyzed 100 CTs of the larynx (200 vocal cords): axial images were acquired through multiplanar reformation to obtain minute details of all subjects. Results: The mean anteroposterior (AP) vocal fold length (VFL) was of 16.8 ± 2.6 (range: 11.8-22.9) mm, which was significantly longer in male subjects (mean = 18.4 ± 2.2 mm; range = 10.9-19.8 mm) compared to female subjects (mean = 15.3 ± 1.95 mm; range = 10.9-22.9 mm). The mean width of the subglottic area was of 14.88 ± 2.18 (range = 8.9-21.1) mm, which was significantly wider in male subjects (15.6 ± 2.13 mm; range = 9.1-21.1 mm) compared to female subjects (mean = 14.18 ± 1.99 mm; range = 8.9-17.8 mm). There was a positive correlation between the AP and transverse diameters of the subglotic area with the VFL: the longer the AP and transverse diameters of the subglottic area, the longer the VFL and vice versa. Conclusion: The present study improves the awareness of surgeons and radiologists of the laryngeal dimensions, and it can be of help to residents in training.
