Assessment of vocal cord movement by ultrasound in the ICU.
Article in Intensive care medicine, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
purposeUltrasound can be used to non-invasively and rapidly examine airway conditions, but vocal cord visualization with the traditional approaches is poor. Our aim was to compare the accuracies of front-side transverse-axis ultrasound (FTU), lateral-side longitudinal-axis ultrasound (LLU), and the combination of both approaches for vocal cord movement disorder diagnoses (e.g., vocal cord paralysis or arytenoid cartilage dislocation).
methodsWe compared FTU, LLU, and the combination of both methods for patients in the intensive care unit (ICU). We used nasal fiber-optic endoscopy to confirm vocal cord injury.
resultsAmong the 120 patients examined, 24 (20%) had vocal cord paralysis. The visualization rate of vocal cords for FTU was 71.7% (assessable, 86; non-assessable, 34), that for LLU was 88.3% (assessable, 106; non-assessable, 14), and that for the combined approach was 96.7% (assessable, 116; non-assessable, 4). The sensitivities and specificities were 58.3% (14/24) and 75% (72/96) for FTU, 91.7% (22/24) and 87.5% (84/96) for LLU, and 100% (24/24) and 95.8% (92/96) for the combined approach. Visualization rates for LLU were significantly higher than for FTU (P = 0.002); FTU + LLU rates were higher than those for FTU (P = 0.001). The difference between LLU and FTU + LLU was not statistically significant (P = 0.025).
conclusionLLU can be used to evaluate arytenoid cartilage activity in ICUs, and the results are highly correlated with the diagnosis of nasal fiber-optic endoscopy. The combination of FTU and LLU shows promise as a rapid primary screening method for vocal cord injury.
