Ultrasonographic measurement of glottal area: A potential biomarker study in young Normophonic adults.

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
purposeAdvancing from previous work on ultrasonography (USG)-aided measures including vocal fold morphology and symmetry, vocal fold length (VFL), vocal fold displacement velocity (VFDV) and its acoustic correlates [1], the present study broadened the investigation by exploring additional parameters such as glottal area during the inhalation phase of quiet breathing (QB), its relationship with VFL, VFDV and acoustic measures such as fundamental frequency (f
methodA total of 117 participants were recruited from our hospital, and USG was performed on them across tasks like QB and vowel phonation (/a/ and /i/). A detailed voice evaluation including perceptual analysis of voice using GRBAS (Grade Roughness Breathiness Asthenia Scale) to grade the voice quality and acoustic analysis using Praat software to measure voice parameters was carried out.
resultsThe mean glottal area during the inhalation phase of quiet breathing (QB) was found to be 1.407 cm² (SD = 0.086 cm²) in males and 1.106 cm² (SD = 0.080 cm²) in females. Significant correlation was found between glottal area and VFL, VFDV and CPP values during /i/ phonation.
conclusionBased on these results, we recommend that USG-aided estimation of glottal area can serve as a potential vocal fold biomarker for clinicians and researchers in laryngology.
