Prevalence of Exercise-Induced Desaturation Among COPD Patients Enrolled in Early Inpatient Pulmonary Rehabilitation.

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
Background: Acute exacerbations of COPD (AECOPDs) may cause exercise-induced desaturation (EID), affecting recovery and rehabilitation outcomes. The prevalence and clinical implications of EID during early postexacerbation pulmonary rehabilitation are unclear. This study aimed to determine the prevalence of EID in COPD patients recovering from AECOPDs, with and without long-term oxygen therapy (LTOT) at rest, and to compare clinical, functional, and physiological characteristics. Methods: This retrospective, multicenter study included 262 COPD patients admitted for inpatient pulmonary rehabilitation after AECOPDs. Participants were stratified by resting oxygen therapy status. EID was defined as a ≥4% fall in peripheral oxygen saturation from baseline with nadir <90% during the 6-minute walking test. Clinical, functional, and physiological parameters were compared across subgroups. Results: Overall, 132 patients (50.4%) exhibited EID. Prevalence was higher in patients on oxygen at rest (61.5%) than in those breathing room air (33.9%, Conclusions: EID is common in COPD patients recovering from AECOPD, especially those receiving LTOT, and is linked to more severe functional impairment. Systematic EID assessment using objective oximetry during early pulmonary rehabilitation may support individualized oxygen titration and exercise prescriptions. Prospective studies are needed to clarify its prognostic implications.
