Impact of Hyaluronic Acid Lip Filling on the Electromyographic Activity of the Orbicularis Oris Muscle in Adult Women.

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
Introduction: The rising use of orofacial harmonization highlights the importance of the lip area, closely linked to the orbicularis oris muscle. This longitudinal study assessed the electromyographic (EMG) activity of the upper and lower orbicularis oris muscle in adult women following hyaluronic acid lip filling. Materials and Methods: Twenty-two adult women, with a mean age of 35.4 ± 12.3 years, were included. EMG was measured during rest, cheek inflation tasks (concurrently and alternately), lip protrusion and compression, and before, 30, and 60 days after lip filling. Differences were significant using Results: Significant EMG differences were found in the upper orbicularis oris muscle (before vs. 30 days, Conclusion: Hyaluronic acid lip filling initially relaxed the orbicularis oris muscle at 30 days. By 60 days, the upper muscle's activity increased, indicating adaptation, while the lower muscle remained less active during cheek inflation, showing distinct functional changes after 60 days.
