Effects of an outpatient pulmonary rehabilitation program on exercise capacity, muscle fatigue, dyspnea, and functional status in post-COVID-19 patients: non-randomized clinical trial.
Article in Frontiers in rehabilitation sciences, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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
Background: COVID-19 may lead to persistent sequelae that impair functional capacity, resulting in dyspnea, fatigue, and limitations in activities of daily living. Objective: To evaluate exercise capacity, fatigue, dyspnea, and functional status in patients following hospitalization for COVID-19 who underwent an outpatient pulmonary rehabilitation program (PRP). Methods: The study was approved by the Research Ethics Committee of UniEVANGÉLICA (approval number 4,296,707; September 24, 2020) and registered at ClinicalTrials.gov (Identifier: NCT04982042). This prospective single-arm non-randomized clinical trial included symptomatic individuals after COVID-19 infection. Exercise capacity was assessed using the Six-Minute Walk Test, muscle fatigue using the Fatigue Severity Scale (FSS), modified Medical Research Council (mMRC) Dyspnea Scale, and functional status using the Post-COVID-19 Functional Status Scale (PCFS). The PRP consisted of cardiorespiratory training and muscle strengthening exercises performed three times per week for six weeks. Results: A total of 54 patients were included (29 in the Ward Group and 25 in the ICU Group). After the PRP, 6MWT distance increased from 428.52 ± 104.5 m to 503.19 ± 98.04 m ( Conclusion: The outpatient PRP was associated with significant improvements in exercise capacity, fatigue, dyspnea, and functional status. Lower baseline exercise capacity predicted greater improvement, regardless of ICU admission.
