Virtual reality intervention for visual perception in schizophrenia-a single blind pilot randomized controlled trial.
Trial report in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06718556 (Virtual Reality Intervention for Visual Perception in Schizophrenia-A Single Blind Pilot Randomized Controlled Trial), which is not on this map. Not yet cited in PubMed.
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.

Abstract
backgroundSchizophrenia is characterized by both psychiatric symptoms and visual perception disorders. While virtual reality (VR) is increasingly used in schizophrenia rehabilitation, its impact on visual perception remains underexplored. This study aimed to investigate the effects of VR intervention on visual perception in schizophrenia.
methodsThis pilot randomized, single-blind controlled trial evaluated the effects of a structured non-immersive VR intervention using the Microsoft Kinect system on visual perception in people with schizophrenia, compared to treatment as usual (TAU) alone. The VR group also received TAU. The visual perceptions of all participants were evaluated with the Motor-Free Visual Perception Test-3rd Edition (MVPT-3). The interventions were carried out for 45 min, 3 days a week for 8 weeks.
resultsThe study was completed by 53 participants who were divided into two groups. VR group (n = 27, 38.00±10.79 years) and control group (individualized occupational therapy–based psychosocial program) (n = 26, 38.53±8.05 years). There was no difference between the groups in all parameters of MVPT-3 before the interventions (p > 0.05). Following the intervention, a significant improvement was observed across all parameters of the MVPT-3 in both groups (p < 0.001). However, the VR group demonstrated statistically larger effect sizes compared to the control group. In particular, the VR intervention yielded large effect sizes on all MVPT-3 parameters (η²>0.14, p < 0.001), indicating a strong and consistent impact on visual perceptual abilities.
conclusionsThe findings from this study provide promising preliminary evidence for the potential effects of non-immersive VR-based interventions in improving visual perception in individuals with schizophrenia. CLINICAL TRIALS NUMBER: NCT06718556 (12/02/2024).
