Effects of myotherapy combined with photobiomodulation on the lips: a randomized clinical trial.
Trial report in CoDAS, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeto compare the maximum pressure, average pressure, and labial resistance of healthy adults undergoing myotherapy combined with photobiomodulation at different doses.
methodsa randomized, double-blind clinical trial was conducted. The non-probabilistic sample consisted of 12 individuals with a mean age of 21.8 years, randomly assigned to three distinct groups for intervention with photobiomodulation. The exercises were the same for all participants. In group 1 (G1), participants received photobiomodulation at a dose of 7 J per point; in group 2 (G2), participants received 9 J per point; and in the placebo group (PG), participants underwent the same procedures as in the other groups, but the device was turned on without being activated (placebo). The wavelength used was infrared. Participants received photobiomodulation three times a week, with a 48-hour interval, for eight weeks. Myotherapy was performed at home by participants three times a day, five times a week, for eight weeks. Clinical assessment of the lips, maximum pressure, average pressure, and labial resistance were conducted using the Iowa Oral Performance Instrument (IOPI) before and after intervention.
resultsThere were no results indicating an increase in maximum or average lip pressure; however, there was an increase in labial resistance in G1.
conclusionPhotobiomodulation associated with myotherapy, with the parameters and methodology used in this study, did not result in an increase in lip pressure but promoted an increase in resistance in the group exposed to 7 J per point.
