Fall risk perception toolkit based on "digital human" for community-dwelling older patients with stroke: development and validation.
Trial report in BMC geriatrics, 2025. 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
backgroundThis study aims to develop a fall risk perception toolkit based on "digital human" (FRP-digital human), test its usability among community-dwelling older patients with stroke, and verify its implementation effect.
methodsThe toolkit underwent three phases: development, usability test, and effectiveness verification. A mixed method usability test was conducted with 20 participants who met the criteria. The toolkit was validated in a 12-week two-arm pilot study involving 80 community-dwelling older patients with stroke. Two groups of participants were randomly assigned to either the intervention or the control group to receive the same content of health education. Intervention group received health education based on "digital human", while control group received traditional online PDF text health education. The usability test contained Post-Study System Usability Questionnaire (PSSUQ), Customer Effort Score (CES), Net Promoter Score (NPS), and user interviews. Rate of Participant (RP), Rate of Adherence (RA), fall risk perception, object fall risk and quality of life were selected as outcome indicators. The corresponding measurement tools were calculation of RP and RA, Fall Risk Perception Scale for community-dwelling older adults (FRPS), Timed Up and Go test (TUG), and the Short Version of the Stroke Specific Quality of Life scale (SV-SS-QoL).
resultsFour functional modules of FRP-digital human were determined. 20 participants completed the usability test. The CES was 3.1, NPS was 4.5 and the overall satisfaction of PSSUQ was 72.14%. Six themes were obtained from user interviews. A total of 80 participants completed the pilot study. The RP was 100% in both intervention group and control group, and significant differences was observed in RA between two groups (P < 0.05). There were statistically significant differences in FRPS and the SV-SS-QoL between two groups (P < 0.001). No statistically significant was observed in TUG between two groups (P = 0.996).
conclusionFRP-digital human can be accepted by community-dwelling older patients with stroke and help improve their fall risk perception and quality of life. Moreover, the design of the WeChat mini program increased its generalizability to promote more successful health care delivery.
