A feasibility study evaluating the usability and acceptability of the personalised space technology exercise platform mobile application.
Observational study in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05830318 (Usability and Acceptability Study of the P-STEP Mobile Application), which is not on this map. Cited by 1 paper.
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.

Abstract
The P-STEP (Personalised Space Technology Exercise Platform) app is designed to bring together tailored exercise guidance and up-to-date air quality information for individuals with long term health conditions. The app allows individuals to plan outdoor exercise walking routes while minimising their exposure to air pollution. Individuals with chronic long-term conditions, particularly respiratory and cardiovascular conditions, can use the app to minimise the risk of their symptoms being worsened by pollution while gaining the benefits of outdoor exercise. This study measured the usability and acceptability of the P-STEP app. The study was a single-arm 12-week pilot study based in Leicestershire, United Kingdom. We recruited 93 participants from an existing cohort study to use and evaluate the app for 12 weeks. Questionnaire data were collected at three timepoints; baseline, 6-weeks and 12-weeks. The primary outcome was the System Usability Scale at 12 weeks. Secondary outcomes included the User Engagement Scale Short Form, SF-12, Recent Physical Activity Questionnaire, bespoke app-specific usability questions and feasibility outcomes. Additional data collected include participant demographic information, technology self-efficacy, and adverse events. Weekly anonymised app usage data were collected and analysed separately to complement the questionnaire data. We assessed 342 individuals for eligibility, of whom 182 (53%) were eligible. Of the 182 eligible, 93 (51%) were enrolled and given access to the app for 12 weeks. Overall, 61 (66%) participants completed the study. At 12 weeks, the mean (sd) System Usability Score was 61.68 (22.9), bespoke usability score was 66.82 (14.75) and User Engagement Score was 3.08 (0.79). Completion rates across all questionnaires were high. Participants accepted the format of online questionnaires, with no participants requiring help to complete and no participants withdrawing from the study for this reason. This study helps to understand the feasibility and acceptability of administering the P-STEP app in a cohort of people with relevant long-term conditions. The results will help inform the design of a future randomised controlled trial.Trial registration The https://clinicaltrials.gov/ ID number is NCT05830318.
