An fNIRS dataset for Multimodal Speech Comprehension in Normal Hearing Individuals and Cochlear Implant Users.

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
Understanding cortical processing in cochlear implant (CI) users is crucial for improving speech outcomes. Functional near-infrared spectroscopy (fNIRS) provides a non-invasive, implant-compatible method for assessing cortical activity during speech comprehension. However, existing studies suffer from methodological heterogeneity and a lack of standardized datasets, limiting cross-study comparisons and generalizability. To address this gap, we present a multimodal fNIRS dataset comprising 46 CI users and 26 normal hearing controls. Participants completed a clinically relevant speech comprehension task using the German Matrix Sentence Test (OLSA) under speech-in-quiet, speech-in-noise, audiovisual and visual speech (i.e., lipreading) conditions. fNIRS recordings covered key cortical regions involved in speech processing, including the prefrontal, temporal, and visual cortices. Additionally, we provide detailed metadata, including patient history, hearing tests, behavioral measures, and spatially registered probe positions. This data descriptor aims to provide a comprehensive resource for investigating multimodal speech understanding in CI users. It enables researchers to explore cortical adaptations in prosthetic hearing, contributing to the refinement of CI rehabilitation strategies and advancing the understanding of auditory neuroplasticity.
