Clinical Profile and Predictors of Asthma-Chronic Obstructive Pulmonary Disease Overlap in a Tertiary Care Population in North India.

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
backgroundAsthma and chronic obstructive pulmonary disease (COPD) are common chronic airway disorders with distinct pathophysiology. A subset of patients exhibits overlapping clinical, functional, and inflammatory features, termed asthma-COPD overlap (ACO), which is associated with increased disease burden and management challenges. Data on the prevalence and characteristics of ACO using standardized criteria in the Indian population remain limited. The present study was conducted to determine the prevalence of ACO and to compare its demographic, inflammatory, and functional characteristics with asthma and COPD, and identify factors associated with ACO.
methodsThis cross-sectional study included 200 clinically stable adults with physician-diagnosed asthma or COPD at a tertiary care center in North India. Patients were classified as asthma, ACO, or COPD using the combined Global Initiative for Asthma (GINA) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) clinical and spirometric criteria. Demographic data, smoking exposure, body mass index (BMI), absolute eosinophil count (AEC), spirometry, resting oxygen saturation (SpO
resultsFifty-one patients (25.5%) met the ACO criteria. The ACO group showed intermediate age, male predominance, and greater smoking exposure. AEC was significantly higher in ACO than in COPD. Post-bronchodilator forced expiratory volume in one second (FEV₁%), SpO
conclusionACO constituted a considerable proportion of patients among those diagnosed with COPD or asthma. Smoking exposure, persistent eosinophilic inflammation, and functional impairment were intermediate between asthma and COPD.
