Feasibility of app-based pulmonary telerehabilitation program for textile dyeing workers with respiratory symptoms: a quasi-experimental study.
Article in Journal of Yeungnam medical science, 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
backgroundTextile dyeing workers are at an increased risk of developing occupational respiratory diseases owing to frequent exposure to harmful chemicals, irritants, and high humidity in the workplace. Pulmonary rehabilitation is essential but associated with access and adherence challenges. This study aimed to evaluate the feasibility, effectiveness, accessibility, and safety of an app-based pulmonary telerehabilitation program for this population.
methodsForty-five textile dyeing workers with respiratory symptoms underwent a 4-week pulmonary telerehabilitation program consisting of daily gamified respiratory muscle training using a Bluetooth-enabled device and video-guided flexibility exercises. The program was delivered through a mobile application and adherence was monitored using an online platform. Pulmonary function tests, 6-minute walk test, hand grip strength, and St. George's Respiratory Questionnaire (SGRQ) scores were assessed at baseline (T0) and post-intervention (T1). The adherence, adverse events, and system usability were evaluated.
resultsImprovements were observed in forced expiratory volume in 1 second (FEV1), FEV1/forced vital capacity, maximal inspiratory pressure, and maximal expiratory pressure at T1 compared to T0. The SGRQ activity scores improved after the intervention. The mean adherence rate was 95.69%; three participants had adherence rates <80% for ≥1 week each. The mean System Usability Scale score was high.
conclusionThe program resulted in significant improvements in pulmonary function and quality of life with high adherence rates and good usability. This may be a promising approach for managing occupational respiratory diseases among textile dyeing workers. Further studies with larger sample sizes and longer follow-up periods are warranted to validate these results and assess the long-term outcomes.
