Subphenotypic classification of COVID-19 survivors and response to telerehabilitation: a latent class analysis.
Trial report in Journal of rehabilitation 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
objectiveInvestigating the role of telerehabilitation in aiding recovery and societal reintegration for COVID-19 survivors, this study aims to identify distinct subphenotypes among survivors and assess their responsiveness to telerehabilitation.
designA secondary analysis of a multicentre, parallel-group randomized controlled trial from April 2020 through to follow-up in 2021. SUBJECTS/PATIENTS: The study included 377 COVID-19 survivors (47.1% male), with a mean age of 56.4 years.
methodsData from the Telerehabilitation Programme for COVID-19 (TERECO) were analysed using Latent Class Analysis to identify subphenotypes based on baseline characteristics. Clinical outcomes were compared between subphenotypes and treatment groups.
resultsLatent Class Analysis identified 2 phenotypes: Phenotype 1 (52.9%) characterized by impaired lung function and Phenotype 2 (47.1%) with better lung function. Among those receiving corticosteroids, only Phenotype 1 showed significant benefits from the TERECO intervention. Discrimination accuracy using forced expiratory volume in 1 s (FEV1) and peak expiratory flow was high (AUC = 0.936).
conclusionTwo distinct phenotypes were identified in COVID-19 survivors, suggesting potential improvements in clinical trial design and personalized treatment strategies based on initial pulmonary function. This insight can guide more targeted rehabilitation approaches, enhancing recovery outcomes for specific survivor groups.
