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
Background: The effectiveness of virtual reality (VR) technology in reducing anxiety and depression among patients with chronic obstructive pulmonary disease (COPD) remains uncertain. This study aimed to evaluate the impact of VR-based interventions on psychological outcomes in patients with COPD through a systematic review and meta-analysis. Methods: A systematic search was conducted in 11 databases, including PubMed, Embase, Web of Science, the Cochrane Library, CINAHL, PsycINFO, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, the Chinese Medical Journal Full-text Database (CMJD), and SinoMed, from database inception to February 11, 2026. Randomized controlled trials (RCTs) assessing the effects of VR interventions on anxiety or depression in patients with COPD were included. Two reviewers independently performed study screening, data extraction, and quality assessment, and the risk of bias was evaluated using the revised Cochrane risk-of-bias tool for randomized trials (RoB 2). Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using a random-effects model in RevMan 5.4, and the certainty of evidence was assessed using the GRADE approach. The primary outcomes were changes in anxiety and depression symptoms. Results: A total of 1,767 records were identified, of which 10 studies involving 673 patients with COPD met the inclusion criteria, and 9 studies were included in the meta-analysis. Because of substantial between-study heterogeneity, a random-effects model was used. Meta-analysis showed that, compared with control groups, VR interventions significantly reduced anxiety levels in patients with COPD [SMD = -1.63, 95% CI (-2.49, -0.78), P = 0.0002, I Conclusion: VR-based interventions show potential for improving anxiety and depressive symptoms in patients with COPD and may serve as a valuable adjunct to conventional pulmonary rehabilitation. Nevertheless, the substantial heterogeneity observed across studies limits the certainty of the available evidence. Consequently, the findings should be interpreted with caution, and further rigorously designed, large-scale RCTs are needed to verify the long-term effectiveness of VR interventions and inform their optimal clinical implementation.
