Effects of an app-based physical training for long- and post-COVID treatment (A PILOT) study: protocol for a multicentre randomised controlled trial.
Article in BMJ open sport & exercise medicine, 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
Long- and post-COVID syndrome (PCS) affect at least 65 million individuals globally, with an estimated incidence of 10% among over 651 million documented cases of SARS-CoV-2 infection. PCS impacts nearly every organ system, posing significant challenges for healthcare systems and patients. Despite this, effective guidelines for multimodal training or rehabilitation remain absent. The app-based physical intervention for long- and post-COVID treatment (A PILOT) study is a prospective, multicentre, two-armed, randomised controlled trial to evaluate the effectiveness of an app-based multimodal training intervention in patients with PCS. 100 participants will be randomly assigned to an intervention group (IG) or a control group (CG). Over 2 months, the IG will follow a standardised app-based intervention programme incorporating breathing exercises, endurance and strength training and progressive muscle relaxation. The CG will adhere to general WHO exercise recommendations during the waiting period and gain access to the app after the study concludes. Comprehensive assessments, including physical examinations, blood tests, psychological questionnaires, transthoracic echocardiography, electrocardiography and cardiopulmonary exercise testing, will be conducted pre- and post-intervention. The primary endpoints are the effects of app-based multimodal training on physical performance, neurocognitive function and health-related quality of life. Secondary endpoints include mental health outcomes (eg, depression, perceived stress, sleep quality and daytime sleepiness), echocardiographic and anthropometric measures and alterations in inflammatory markers and metabolites of the kynurenine pathway. This study aims to provide critical insights into structured app-based programmes, potentially establishing a framework for improving recovery in PCS patients.
