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
Background: Dichotic listening tests, such as the Dichotic Digit Test (DDT) developed by F. Musiek, are vital for assessing auditory processing disorders. There is a lack of validated auditory tests in Italian, necessitating the adaptation of existing tools. Objective: This study aims to provide a preliminary assessment of the reliability and normative data for the newly adapted Italian version of the DDT. It hypothesises that the Italian DDT will show comparable reliability and normative data to the original English version, with a similar Right-Ear Advantage (REA). Methods: The adaptation process involved a pilot study with 20 normal hearing adults, comparing the English and Italian versions of the DDT. Subsequently, the study included 138 children aged 6-10 years, using the Italian version to assess test-retest reliability and gather normative data. Results: The findings revealed a consistent REA across participants that was more pronounced in younger children. The Italian version of DDT demonstrated adequate reliability across age groups and gender, with test-retest stability observed in both adults and children. Conclusions: This preliminary study provides essential data on the reliability and normative scores of the Italian DDT. The findings support its use in clinical and research settings, although further studies are required for comprehensive validation.
