Outdoor nature-based activities for mental vitality and cognitive empowerment in older adults: a randomized controlled trial protocol.
Article in Trials, 2026. 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
backgroundNature exposure has been associated with mental health and cognitive benefits among older adults. However, controlled trials evaluating specific types of nature-based interventions are limited. This study aims to examine the effects of two structured outdoor activities, walking with meaningful conversation and group meditation, on mental vitality and cognitive empowerment in elderly women.
methodsThis is a three-arm parallel randomized controlled trial (RCT) enrolling 111 women aged ≥ 60 from 9 urban and rural health centers in Khafr County, Iran. Participants will be randomized into the following: (1) Walking with meaningful conversation group, (2) meditation in nature group, and (3) control group with no intervention. Each intervention consists of eight 2-h sessions across 8 weeks. Assessments will occur at baseline, post-intervention (week 8), and 3-month follow-up using validated questionnaires on mental vitality and cognitive empowerment. The generalized estimating equation (GEE) model will be applied to analyze changes over time. DISCUSSION: We hypothesize that both intervention groups will show significant improvements compared to the control, with walking expected to yield greater gains in mental vitality and meditation to better enhance cognitive empowerment. Findings may support the implementation of community-based, non-pharmacological programs to promote active aging.
