Objectively Measuring Audiovisual Effects in Noise Using Virtual Human Speakers.
Article in Trends in hearing. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Speech intelligibility in challenging listening environments relies on the integration of audiovisual cues. Measuring the effectiveness of audiovisual integration in these challenging listening environments can be difficult due to the complexity of such environments. The Audiovisual True-to-Life Assessment of Auditory Rehabilitation (AVATAR) is a paradigm that was developed to provide an ecological environment to capture both the audio and visual aspects of speech intelligibility measures. Previous research has shown the benefit from audiovisual cues can be measured using behavioral (e.g., word recognition) and electrophysiological (e.g., neural tracking) measures. The current research examines, when using the AVATAR paradigm, if electrophysiological measures of speech intelligibility yield similar outcomes as behavioral measures. We hypothesized visual cues would enhance both the behavioral and electrophysiological scores as the signal-to-noise ratio (SNR) of the speech signal decreased. Twenty young (18-25 years old) participants (1 male and 19 female) with normal hearing participated in our study. For our behavioral experiment, we administered lists of sentences using an adaptive procedure to estimate a speech reception threshold (SRT). For our electrophysiological experiment, we administered 35 lists of sentences randomized across five SNR levels (silence, 0, -3, -6, and -9 dB) and two visual conditions (audio-only and audiovisual). We used a neural tracking decoder to measure the reconstruction accuracies for each participant. We observed most participants had higher reconstruction accuracies for the audiovisual condition compared to the audio-only condition in conditions with moderate to high levels of noise. We found the electrophysiological measure may correlate with the behavioral measure that shows audiovisual benefit.
