Modification of Masticatory Rhythmicity Leading to the Initiation of the Swallowing Reflex in Humans.
Article in Dysphagia, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Modification of movements by proprioceptive feedback during mastication has an important role in shifting from the oral to the pharyngeal phase of swallowing. The aim of this study was to investigate the kinetics of masticatory muscles throughout a sequence of oropharyngeal swallowing and to present a hypothetical model of the involvement of the nervous system in the transition from mastication to the swallowing reflex. Surface electromyographic signals were recorded from the jaw-closing masseter muscles and the jaw-opening suprahyoid muscle group when a piece of bread (3-5 g) was ingested. Participants were not provided any additional instruction regarding how to chew and swallow. In the final stage of mastication, compared with other stages of mastication, the duration between sequential peak times of rhythmic activity of the masseter muscles was prolonged. Electromyography revealed no significant change in the suprahyoid muscle group. Accordingly, contraction of the jaw-closing muscles and the jaw-opening muscles altered from out-of-phase to in-phase. We have presented a hypothetical model based on the results of the present study, in which mastication shifts to the swallowing reflex when feed-forward inputs from rhythm generators for the jaw-closing and the jaw-opening muscles converge onto an assumed "convertor" neuron group concurrently. This model should contribute to understanding the pathophysiology of dysphagia.
