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
objectiveThe aim of this study is to investigate short-term changes in the electromyographic (EMG) activity of masticatory muscles in individuals with skeletal Class III malocclusion undergo double-jaw orthognathic surgery. MATERIAL AND
methodsIn patients with skeletal Class III anomaly, EMG activity changes in the anterior temporalis and masseter muscles were measured before T0 and at 3 (T1) and 6 (T2) months after bimaxillary orthognathic surgery. Recordings were obtained using the 'MP100' device and circular Ag-AgCl electrodes during closure, clenching, chewing and swallowing. Data from 26 individuals (12 males, 14 females) with a mean age of 21.7 years were analysed using the Friedman test.
resultsA significant decrease was observed in the right/left masseter muscles during clenching/chewing from T1 to T0 (right and left masseter clenching: p < 0.001, left masseter chewing: p < 0.01, right masseter chewing: p < 0.05), while a significant increase was noted in the right masseter's clenching function from T2 to T1 (p < 0.01). The EMG activity of the right anterior temporal muscle decreased during clenching at T1-T0 (p < 0.001), increased at T2-T1 (p < 0.05), and decreased during chewing/swallowing at T1-T0 (chewing: p < 0.001, swallowing: p < 0.05) and T2-T0 (p < 0.05). The left anterior temporal muscle showed decreased EMG activity during clenching at T1-T0 (p < 0.001), increased at T2-T1 (p < 0.05), and decreased during chewing at T1-T0 (p < 0.001). During swallowing, a decrease was observed at T2-T0 (p < 0.001).
conclusionsPartial changes in EMG activity were observed during some functions in the 3-month period; however, no significant overall change was recorded in the 6-month period.
