Therapeutic device as a facilitating resource for esophageal voice acquisition.
Article in Brazilian journal of otorhinolaryngology, 2026. 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
objectiveTo describe the findings on the use of a therapeutic device for direct esophageal stimulation, which facilitates the production of the esophageal voice.
methodFifteen total laryngectomized subjects, with no voice production and no success in traditional speech-language pathology therapies for esophageal voice acquisition, participated. Subjects were evaluated using a specific vocal quality protocol for total laryngectomy, videofluoroscopy, and a vocal self-assessment questionnaire before and after 12 sessions of esophageal stimulation with the device. To stimulate esophageal voice acquisition, direct esophageal stimulation was performed using a catheter with a total length of 50 cm, which was introduced from the nostril until reaching the pharyngoesophageal segment; the other end of the catheter was fixed to the tracheostoma. The intervention occurred over 12 consecutive weeks, without interruption. Descriptive and inferential statistical analysis was performed at a 5% significance level.
resultsNine (60%) subjects developed effective esophageal voice for communication, while 6 (40%) managed to develop esophageal sound. Auditory-perceptual evaluation did not show statistically significant differences between pre- and post-intervention moments; however, participants' self-assessment indicated perceived improvement in vocal quality.
conclusionEsophageal stimulation with the proposed device was associated with improvements in patients' self-assessment and enabled a proportion of subjects to achieve functional esophageal voice. The device may represent a feasible therapeutic resource. LEVEL OF EVIDENCE: 2B - Prospective interventional study without control group.
