1 · What the graph read from it

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.

2 · The registry

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

This study presents a standardized naturalistic audio stimulus dataset designed for use in trial-wise cognitive neuroscience, neuroimaging, and behavioral research. The dataset provides short, recognizable auditory stimuli that are normed for emotional valence and startlingness. To create such a dataset, the current study collected 291 audio files from a range of sources and standardized them to a duration of 1.5 s. A final sample of 361 participants rated the audio clips on emotional valence, startlingness, and recognizability, and subsequently freely described the audios by typing what they believed the sound to be. The text responses of the participants were embedded and clustered using an unsupervised machine-learning algorithm to derive a participant-grounded organization of auditory object categories. The results indicate that the audio clips were generally recognizable, while emotional valence and startlingness ratings varied across stimuli.
