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

backgroundPreoperative anxiety is a common yet often neglected problem for patients undergoing surgery. Virtual reality (VR)-based intervention is a promising alternative with benefits for managing preoperative anxiety. However, the components of VR-based intervention and its effectiveness on preoperative anxiety in patients undergoing elective surgery with anesthesia remain unclear.

objectiveThis study aimed to identify the major components (ie, device, medium, format, and duration) of VR-based interventions and summarize evidence regarding their effectiveness in reducing preoperative anxiety in patients undergoing elective surgery with anesthesia.

methodsAllied and Complementary Medicine, Chinese University of Hong Kong Full Text Journals, CINAHL via EBSCOhost, Cochrane Library, Joanna Briggs Institute EBP Database, EMBASE, MEDLINE via OvidSP, PubMed, PsychINFO, Scopus, China Journal Net, and WanFang Data Chinese Dissertations Database were searched from inception to February 2025. Randomized controlled trials (RCTs) of VR-based interventions for patients undergoing elective surgery with anesthesia were included. The Cochrane Collaboration's tool was used for risk of bias assessment. A random effect model was used for pooling the results.

resultsA total of 35 RCTs with 3341 patients (female: n=1474, 44.1%) were included in this review, of which 29 RCTs were included for meta-analysis. Compared with usual care, VR-based interventions showed substantial benefits in decreasing preoperative anxiety in patients undergoing elective surgery (standardized mean difference [SMD] 0.65, 95% CI 0.37-0.92; P<.001). Regarding the subgroup analysis, VR-based intervention showed significant but moderate effects on preoperative anxiety in the pediatric population (SMD 0.77, 95% CI 0.32-1.22; P<.001) compared to the adult population (SMD 0.58, 95% CI 0.23-0.93; P=.001). The distraction approach showed more significant effects (SMD 0.73, 95% CI 0.24-1.21; P=.004) on preoperative anxiety than the exposure approach (SMD 0.61, 95% CI 0.27-0.95; P<.001).

conclusionsPatients undergoing elective surgery with anesthesia may benefit from VR as a novel alternative to reduce preoperative anxiety, especially pediatric patients via the distraction approach. However, more rigorous research is needed to confirm VR's effectiveness.
