Cardiopulmonary Exercise Testing for Prognostic Assessment of Clinical Outcomes in COPD: A Systematic Review and Meta-Analysis.

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
Chronic obstructive pulmonary disease (COPD) is a heterogeneous, progressive lung disorder. Despite its high prevalence, predicting clinical outcomes remains challenging. Various cardiopulmonary exercise testing (CPET) variables have been suggested as prognostic markers in COPD, but their role in clinical practice remains unclear. After registration in PROSPERO (ID CRD42024569879), a literature search of the Pubmed, Embase, Web of Science, Cochrane library and Scopus databases was carried out in August 2024. Study selection followed the PRISMA guidelines. Prospective and retrospective cohort studies evaluating associations between CPET variables and clinical outcomes in patients with COPD were included. Risk of bias was evaluated using the QUIPS tool. Data were extracted and synthesized narratively. A random-effects meta-analysis was planned if multiple studies reported comparable CPET variables, outcomes, and effect measures. Sixteen articles were included, three of which had an overall high risk of bias. Peak oxygen uptake (VO
