Is vocal cord asymmetry seen on transcutaneous laryngeal ultrasonography a significant predictor of voice quality changes after thyroidectomy?
Trial report in World journal of surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundVocal cord asymmetry (VCA) on laryngoscopic examination (LE) may suggest voice impairment after thyroidectomy, but LE may cause patient discomfort. We aimed to correlate the presence of postoperative VCA assessed by noninvasive transcutaneous laryngeal ultrasonography (TLUSG) with voice quality changes after thyroidectomy.
methodsA total of 169 patients scheduled for thyroidectomy completed two validated voice symptoms questionnaires-the GRBAS (grade, roughness, breathiness, asthenia, strain) scale and the voice impairment score (VIS)-and underwent TLUSG and LE at 1 day before and 7-10 days after thyroidectomy. Postoperative VCA was apparent in 51 patients on TLUSG (group I), whereas there was no VCA in the other 118 patients (group II, controls). The GRBAS scale and VIS results were compared between the groups.
resultsBefore operation, the two groups had comparable preoperative GRBAS and VIS status. After operation, the "grade" and "roughness" components on the GRBAS scale were significantly worse in group I than in group II: 0.24 versus 0.07 (p = 0.016) and 0.33 versus 0.14 (p = 0.022), respectively. "Grade" and "roughness" in the GRBAS scale significantly worsened after the operation in group I: from 0.04 to 0.24 (p = 0.008) and from 0.02 to 0.33 (p = 0.001), respectively. They did not change in group II. Also, the overall VIS was significantly worse after thyroidectomy in group I: 4.97 versus 12.97 (p < 0.001).
conclusionsVCA seen on TLUSG significantly correlated with "grade" and "roughness" components on the GRBAS scale and the overall VIS. Thus, VCA might be used as a surrogate of postoperative voice changes.
