Correlation Between Chronic Obstructive Pulmonary Disease Severity and Nutritional Status: A Cross-Sectional Study From a Tertiary Care Center in South India.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Introduction Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality worldwide. Malnutrition is a common and under-recognized comorbidity in COPD, impacting muscle function, immune response, and disease progression. Methods A cross-sectional observational study was conducted on 150 COPD patients at a tertiary care hospital in Chennai. Nutritional status was assessed using body mass index (BMI), mid-arm circumference (MAC), and Mini Nutritional Assessment (MNA) scores. COPD severity was graded according to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2025 criteria. Results A significant positive correlation was observed between forced expiratory volume in one second (FEV
