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

backgroundHemispatial neglect affects approximately 33% of patients after acute stroke and is linked to poor recovery. Auditory motion stimulation, particularly using spatial cues, can enhance spatial awareness and has shown promise in experimental settings.

objectiveThis study aimed to develop and evaluate Neglect Radio, a smartphone app that delivers auditory motion stimulation, focusing on sound realism and usability in healthy volunteers.

methodsTwo auditory motion rendering methods, dynamic stereo volume control and standardized head-related transfer functions (HRTFs), were implemented in a mobile app streaming public radio content. In an online study, 37 healthy volunteers rated spatial realism (0-100 scale) of 5 audio sources in 3 conditions: static stereo, volume control motion, and HRTF-based motion. Independent samples 1-tailed t tests compared realism scores. Ten participants tested the app for 15 minutes and completed the System Usability Scale (SUS).

resultsHRTF-based audio was rated as being significantly more realistic than volume control (t

conclusionsNeglect Radio successfully produced realistic spatial auditory motion and achieved excellent usability ratings in healthy participants. This smartphone-based platform is scalable, accessible, and engaging, with potential to complement hemispatial neglect rehabilitation. However, clinical efficacy in stroke patients with hemispatial neglect has not yet been evaluated and requires confirmation in controlled trials.
