Linking brain activation to clinical outcomes: an fNIRS study in cochlear implant users and normal hearing individuals.

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
Significance: Cochlear implants (CIs) are a proven intervention for severe hearing loss; however, outcomes vary widely among CI recipients. Emerging evidence suggests that cortical adaptation to the electric hearing provided by CIs play a crucial role. Aim: We investigate cortical brain activation differences in CI users, comparing individuals with good speech understanding (good performers, GP) to those with poor outcomes (poor performers, PP) alongside a control group with normal hearing (NH). Approach: We recruited 46 CI users and 26 NH participants to perform a clinically adapted audiovisual speech comprehension task while we measured their brain activity using functional near-infrared spectroscopy (fNIRS). We corroborated our findings with objective and behavioral data. Results: Our findings showed distinct brain activation patterns associated with speech understanding. GP showed comparable brain activation patterns to NH in audio-only conditions, indicative of successful hearing rehabilitation. Further, both GP and PP participants showed an adaptive mechanism during visual speech processing. However, compared with GP, PP relied heavily on visual cues and showed altered neural resource allocation during audio-only conditions, potentially limiting their overall rehabilitation success. Conclusions: fNIRS revealed significant differences in brain activation between GP and PP, highlighting the role of cortical factors in CI rehabilitation. Understanding these neural mechanisms has the potential to lead to better patient counseling, optimized postoperative management, and personalized therapeutic strategies to improve outcomes for CI users.
