Correlation Between COPD Assessment Test (CAT) Scores and the BODE Index in Stable Chronic Obstructive Pulmonary Disease (COPD): A Prospective Observational Study.
Article in Cureus, 2026. 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
Background Chronic obstructive pulmonary disease (COPD) remains a leading cause of global morbidity and mortality, yet its clinical assessment continues to rely heavily on spirometry, which inadequately reflects patient-centred disease burden. The need for rapid, scalable, and clinically meaningful assessment tools is particularly critical in resource-constrained settings. This study explores whether the COPD Assessment Test (CAT), a simple symptom-based instrument, correlates strongly with multidimensional prognostic indices such as the Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity (BODE) index. Methods A prospective observational study was conducted on 60 stable COPD patients. Clinical, demographic, and exposure data, including smoking and biomass exposure, were systematically recorded. All patients underwent spirometry and assessment using the CAT score and the BODE index. Correlation analysis using Pearson's coefficient was performed to evaluate relationships between the CAT score, BODE index, and forced expiratory volume in one second (FEV
