Surface Electromyography of Pharyngeal Swallowing in Healthy Chinese Individuals: Establishment of a Timing and Amplitude Database.
Article in Dysphagia, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This study determined the surface electromyography (sEMG) characteristics of healthy Chinese adults during swallowing to provide a reference for the clinical differential diagnosis of swallowing and dysphagia. sEMG was performed on 187 healthy adults to obtain quantitative information on normal pharyngeal swallowing. The evaluated parameters included the timing and amplitude of sEMG activity in the submental and infrahyoid muscles. A normative database was constructed for the timing and amplitude of muscle activity during pharyngeal swallowing. Results indicated that the duration of sEMG activity was related to the age of the patient; the duration gradually increasing with age. Similarly, the duration of the sEMG activity was associated with the type of swallowing. The duration of the sEMG activity was similar for dry and wet swallowing but was significantly different for excessive swallowing. The mean amplitude of sEMG activity for the submental and infrahyoid muscles was not significantly associated with patient age. A significant correlation between the mean amplitude of sEMG activity and the types of normal swallowing was observed in infrahyoid, but not in submental muscle activity. This study is the first report on the establishment of a normative database for the duration and amplitude of muscle activity based on sEMG analysis of pharyngeal swallowing in healthy Chinese adults.
