Influence of colors in distractor videos on the recording of cortical auditory evoked potentials.
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 compare the morphological differences in CAEP obtained with black-and-white versus colored distractor videos, and to verify whether the black-and-white format reduces response variability.
methodsThis cross-sectional analytical study, approved by an ethics committee (protocol nº 3.477.022), included 30 adults aged 18-35 years with normal hearing. Participants underwent CAEP recordings using /ba/ and /da/ stimuli under two conditions: silent black-and-white and silent colored videos. Latencies, amplitudes, and interlatency intervals were analyzed using paired t-tests and Levene's test (p < 0.05).
resultsColored videos resulted in longer latencies for P1 and P2 in both ears, reduced P1 amplitude in the right ear, and increased P2 amplitude bilaterally. The P1-N1 interval was greater with black-and-white videos, while the N1-P2 interval increased with colored videos in the left ear.
conclusionThe use of colored videos influences CAEP morphology and variability and should be carefully considered in clinical and research contexts.
