Effects of indoor biophilic environments on cognitive function in elderly patients with diabetes: study protocol for a randomized controlled trial.
Article in Frontiers in psychology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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 prevalence of cognitive impairment in elderly diabetic patients is increasing, highlighting the importance of exploring strategies to prevent and ameliorate cognitive impairment in this population. Previous studies have focused mostly on improving cognition in elderly diabetic patients through three methods: medication, cognitive training, and lifestyle intervention. However, few studies have investigated the role of indoor biophilic environments in improving cognition. Biophilic environments improve human health by integrating natural elements into indoor architectural settings and have demonstrated efficacy in reducing stress and improving cognition. Therefore, it is worth exploring the effects of indoor biophilic environments on cognition in elderly diabetic patients. This study aims to investigate the effects of indoor biophilic environments on cognition in elderly diabetic patients, and the potential mechanisms. Methods: This is a single-center, randomized controlled trial, which includes a short-term VR intervention and a long-term real environment intervention. In the short-term intervention trial, 64 diabetic patients over 60 years old are randomly assigned to 1 of 7 intervention groups or a control group. All intervention groups are constructed by single or various combinations of the 3 indoor biophilic elements: natural decorative paintings, indoor potted plants, and ornamental fish. The primary outcome of the short-term intervention trial is the cognitive scores assessed by DSST and BDS. In the long-term intervention trial, 240 diabetic patients over 60 years old will be randomly assigned to either the intervention group or the control group. The biophilic elements in long-term intervention will be determined based on the results of the short-term VR intervention trial. The primary outcomes of the long-term intervention trial are cognitive scores measured by DSST and MoCA, as well as concentrations of plasma p-tau181, esRAGE, and IL-6. Conclusion: The findings will be utilized to develop a restorative living environment for elderly patients with diabetes to improve cognition.
