Prognostic Factors for Responders of Home-Based Pulmonary Rehabilitation-Secondary Analysis of a Randomized Controlled Trial.
Article in Healthcare (Basel, Switzerland), 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
backgroundHome-based pulmonary rehabilitation (PR) is an effective alternative to center-based PR. However, not all participants exhibit sufficient therapeutic improvement, highlighting the need to identify appropriate candidates to maximize cost-effectiveness. This study aimed to identify the factors associated with favorable outcomes in home-based PR, focusing on the role of digital therapeutics (DTx).
methodsThis secondary analysis used data from a randomized controlled trial. Participants with chronic respiratory disease (CRD) were divided into responders and non-responders based on a change in 6 min walk distance (6MWD) and patient-reported outcome measures (PROM) representing dyspnea and health-related quality of life. Factors such as baseline 6MWD, DTx use, and pulmonary function were analyzed for their predictive value in improving 6MWD and PROM scores.
resultsResponders, particularly those using DTx, showed significantly greater improvements in 6MWD than non-responders. Participants with a baseline 6MWD under 500 m demonstrated a higher likelihood of exceeding the minimum clinically important difference in 6MWD. DTx use strongly predicted improvements in both 6MWD and PROM scores. The baseline diffusing capacity of the lungs for carbon monoxide was also a significant factor influencing improvements in the modified Medical Research Council scale.
conclusionsResponders to 8-week program of home-based PR exhibited a relatively lower baseline health status. Encouraging participants with poorer baseline health could improve adherence to PR and enhance cost-effectiveness. Additionally, improvements in 6MWD and PROM scores were associated with the use of DTx. Considering the functions of DTx, proper supervision for home-based exercise may be crucial for achieving optimal outcomes.
