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
Objectives: This study aims to develop immersive virtual reality (VR) versions of the box and block test (BBT), the 360° turn test, and five times sit-to-stand (5TSTS) test to evaluate functional status within a VR-mediated gamified environment and assess their concurrent validity. Patients and methods: Thirty participants (18 males, 12 females; mean age: 59.9±11.9 years; range, 25 to 82 years) with a stroke diagnosis were included in the prospective study between February 2024 and August 2024. Each participant completed the BBT, 360° turn test, and 5TSTS test three times using both VR-based and traditional methods. Concurrent validity was examined by analyzing the correlations between VR-mediated and traditional test results. The test-retest reliability of the VR-based assessments was evaluated using intraclass correlation coefficients (ICCs). The usability of the developed software was also assessed using the System Usability Scale. Results: Strong correlations were found between VR-based and traditional assessment methods for the affected side in the BBT (r=0.562; p<0.001), in the 360° turn test (r=0.838; p<0.001), and 5TSTS (r=0.733; p<0.001). Interrater reliability was high and statistically significant across all tests (ICC >0.80, p<0.001). The usability of the developed software was rated as good (mean System Usability Scale score: 70.8±15.6). Conclusion: The VR-based versions of the BBT, 360° turn test, and 5TSTS are valid, reliable, and user-friendly tools for assessing functional status in stroke patients. These assessments show promise for integration into clinical settings and remote rehabilitation programs.
