Speech therapy program for the rehabilitation of smell.
Article in CoDAS, 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
purposeTo evaluate the effectiveness of a speech-language pathology-based therapeutic intervention for olfactory dysfunctions.
methodsThe speech-language olfactory rehabilitation program was applied to eight patients with complaints of reduced olfaction due to persistent post-viral infection (1 to 2 years post-infection) and confirmed hyposmia, as determined by the Connecticut Chemosensory Clinical Research Center test. The intervention consisted of 13 in-person sessions of 45 minutes each (the first and last for assessment), which included strategies aimed at increasing awareness of olfaction; nasal breathing and the need for frequent hygiene (nasal and intraoral); perception, identification, and contextualization of odor stimuli using four primary odors; the Nasal Airflow-Inducing Maneuver; as well as taste association and home-based training using the MedSmell® olfactory training kit, three times per day. The project was previously approved by the ethics committee and registered in the Brazilian Registry of Clinical Trials.
resultsThe patients had a mean age of 53.29 ± 21.92 years, with an even distribution between the sexes. All patients showed improvement in olfactory function: six (75%) recovered to normosmia, one (12.5%) improved from anosmia to moderate hyposmia and another (12.5%) from anosmia to mild hyposmia. The olfactory training kit was used daily at home, and all patients completed the program, reporting perceived therapeutic benefits.
conclusionThe speech-language pathology intervention was effective in the rehabilitation of olfactory disorders of viral origin, though further studies with larger samples are needed to generalize the results.
