Primitive audiovisual integration of speech.
Article in Attention, perception & psychophysics, 2025. 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
An unintelligible video recording of a face uttering a sentence and an unintelligible acoustic sinusoid following the frequency variation of a single vocal resonance of the utterance were intelligible when presented together at their veridical synchrony. The intelligibility resulted from audiovisual sensory integration and phonetic perceptual analysis, which depended neither on the separate resolution of linguistic impressions in each modality nor on closed-set reports about a single pair of minimal phonemic contrast features. Likewise, audiovisual integration could not be attributed to Gestalt-derived similarity principles applied unimodally or bimodally. A single sinusoid lacks natural vocal quality, yet was perceptually coherent with the visible form of a natural articulating face. In other tests, integration also survived desynchronization of the two sensory streams, though only if the visible component led the audible component. These measures expose the robust action and temporal dynamic of early non-phonetic sensory integration which can occur in audiovisual speech perception.
