Right-Ear Advantage for Unaided and Aided Speech Perception in Noise in Older Adults.
Article in The journal of international advanced otology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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 investigate whether the magnitude of the right-ear advantage (REA) for speech perception in noise decreased in aided conditions as compared with unaided conditions in older adults bilaterally fitted with hearing aids. A secondary aim was to determine the effect of audibility on the right- and left-ear processing for speech stimuli in both aided and unaided conditions.
methodsForty-two older adult, bilateral hearing-aid users were selected. Pure-tone audiometry and the hearing-in-noise test (HINT) were carried out and real-ear insertion gain (REIG) was measured in all participants. All HINT stimuli were delivered via loudspeakers in the free field in both aided and unaided conditions.
resultsRight-ear scores for HINT were significantly better than the left ear in both unaided and aided conditions. No significant differences in the magnitude of the REA between the unaided HINT and aided HINT scores were found. Regression models showed that audibility explained 47% and 53% of the variance in unaided HINT scores in the right and left ears, respectively. For the aided HINT scores, age and audibility explained 46% of the variability for the left-ear scores, while for the right ear, the only remaining significant variable in the model was REIG, which explained 12% of the right-ear HINT scores.
conclusionRight-ear processing is significantly more efficient for speech stimuli in both unaided and aided conditions in older adults. Audibility affected unaided speech perception in right and left ears similarly however this was not the case in the aided condition. Audibility was associated with aided speech perception in noise in the left ear only.
