Preliminary study of a Digital Brazilian Portuguese Speech Assessment Instrument: validity and reliability of imitation and naming tasks.
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 psychometric properties of the naming and imitation tasks of the Digital Speech Assessment Instrument.
methodsForty-five Brazilian Portuguese (BP)-speaking children aged 4 to 9 years, with and without Phonological Disorder (PD) participated in the study. Construct validity was verified by convergent validity, criterion validity was analyzed using Student's t-test for independent samples, and inter-rater reliability was assessed.
resultsThe naming task demonstrated satisfactory construct validity. In the imitation task, correlations ranged from moderate to nearly perfect. Both tasks discriminated well between groups, with children with PD presenting consistently lower scores. Inter-rater agreement was substantial to nearly perfect.
conclusionThe results indicate that the naming and imitation tasks of the Digital Speech Assessment Instrument are valid and reliable.
