Comparison of Pharyngoesophageal Segment Biomechanics Between Persons with Total Laryngectomy With and Without Dysphagia Using sEMG: A Multicentric Swallow Study.
Article in Dysphagia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Total laryngectomy (TL) is the surgical treatment option for advanced stage of laryngeal cancer, involving the removal of larynx along with several muscles attached to it. Several anatomical changes occur following the surgery which will in turn affect the swallowing mechanism. The severing of the cricopharyngeus muscle, which is an important muscle of the pharyngoesophageal segment (PES), may lead to dysphagia. Several other causes have also been explained in the literature. Several invasive instruments have been used to identify dysphagia in this population. The present study aimed to identify the differences in the biomechanics of the PES during dry and wet swallow tasks in persons with TL with and without dysphagia. Amplitude and duration of movement of PES was analysed using a non-invasive instrumental method surface electromyography. The results indicate that amplitude of PES movement was significantly higher in dysphagic group for solids and semisolids. A significantly longer duration was observed for solid consistency for dysphagic group when compared to non-dysphagic group. sEMG evidences suggestive of differences in amplitude and duration between the TL with and without dysphagia groups. Findings also revealed that TL with dysphagia group require more effort to swallow solids and semisolid consistencies when compared to the effort exerted by them during liquid and dry swallow.
