A Virtual Reality-Based Cognitive Restorative Intervention Using Nature to Improve Attention, Self-Care, and Health-Related Quality of Life in Heart Failure.
Trial report in The Journal of cardiovascular nursing. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
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
backgroundCognitive dysfunction is prevalent and predictive of worse health outcomes among people with heart failure (HF).
objectiveThe purpose of this study was to test the preliminary efficacy of the newly developed virtual reality-based cognitive restorative intervention using nature environments (Nature-VR) on improving attention, HF self-care, and health-related quality of life (HRQL) compared with the active control condition using urban environments (Urban-VR). Intervention effects were explored on other cognitive domains.
methodsA 2-group single-blind pilot randomized controlled trial design was used. Participants randomized to Nature-VR viewed spherical images of nature environments on a virtual reality headset for 10 minutes/day, 5 days/week for 4 weeks (200 images total). Participants randomized to Urban-VR viewed spherical images of urban environments matched to Nature-VR intervention delivery mode and time. Data were collected at baseline, 4, 8, 26, and 52 weeks.
resultsOf 73 participants, 68 (93%) completed the intervention or control condition. Fifty-one (70%) completed the study. Linear mixed models showed no significant group-by-time interactions on attention, HF self-care, or HRQL. Significant time effects were found on HF self-care (all scales, P < .001). Executive function measured by Verbal Fluency Test-Letter F improved more among participants in Nature-VR than those in Urban-VR at 4 weeks ( P = .041) after adjusting covariates.
conclusionsPreliminary efficacy of Nature-VR compared with Urban-VR was not demonstrated for attention, HF self-care, and HRQL. There was preliminary evidence of improved executive function at 4 weeks. Factors associated with intervention responsiveness and strategies to optimize cognitive interventions should be considered.
