An Automated Virtual Reality Cognitive-Behavioural Preventive Intervention for Adults with Agoraphobic Symptoms: A Randomized Controlled Trial of Adapted gameChange in Hong Kong.

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
<p>Introduction: Agoraphobic avoidance, fear of situations that seem hard to escape, is common across mental disorders and often remains untreated due to stigma and limited service access. Automated virtual reality (VR) exposure therapy offers a scalable alternative by enabling safe, guided simulations of feared situations. This randomized controlled trial evaluated the efficacy of a culturally adapted version of gameChange VR for reducing agoraphobic avoidance among adults in Hong Kong without psychiatric diagnoses.
methods272 participants were randomly assigned to either a three-session VR intervention (n = 146) or a waitlist control condition (n = 126). Assessments were conducted at baseline, 3-week, and 1-month follow-ups. Compared to the control condition, participants in the VR intervention condition showed significant reductions in the primary outcome of agoraphobic avoidance (Cohen's d = 0.89), and all the secondary outcomes of agoraphobic distress (d = 1.0), social anxiety (d = 0.91), fear of negative evaluation (d = 0.68), generalized anxiety (d = 0.50), depressive symptoms (d = 0.67), and functional impairment (d = 0.85) at 3 weeks.
resultsSignificant group differences for all outcomes remained at the 1-month follow-up. Higher baseline levels of agoraphobic symptoms were associated with larger improvements in agoraphobic avoidance.
conclusionThese findings suggest that the automated VR intervention is effective in reducing agoraphobic symptoms in non-clinical populations and appears to be a scalable treatment in Asia where stigma is strong. Future studies could include longer follow-ups and address pandemic-related confounds on avoidance behaviours. </p>.
