Low dietary quality in patients with COPD and the association with disease severity: A cross-sectional study.
Article in Asia Pacific journal of clinical nutrition, 2025. 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 AND
objectivesDietary nutrition plays an essential role in the progression of chronic obstruc-tive pulmonary disease (COPD). This study aimed to use Chinese Healthy Eating Index (CHEI) to evaluate dietary quality in COPD patients and investigate the relationship between dietary quality and COPD disease severity. METHODS AND STUDY
designA total of 525 COPD inpatients were collected from December 1st, 2022, to December 1st, 2023. The dietary intake was collected through food frequency questionnaires (FFQ), and diet quality was assessed by the CHEI. Modified Medical Research Council Dyspnea Scale (mMRC), the COPD assessment test (CAT), and Global Initiative for Obstructive Lung Disease (GOLD) stage were used to assess disease severity. Multivariable logistic regression was used to analyze the association between the total CHEI score, and its component scores and COPD disease severity.
resultsThe CHEI score with COPD pa-tients is 56.75±8.89. The CAT score of the low CHEI group was significantly higher than that of the high CHEI group (p <0.05). Ordinal logistic regression analysis indicated that the group with higher CHEI total scores was significantly associated with the low grade of mMRC (OR: 0.982, 95%CI: 0.964, 1.000, p <0.05). And the higher intake of tubers, whole grains and mixed beans, and fish and seafood were all associated with lower mMRC grades (p <0.05).
conclusionsCOPD patients have poor dietary quality. High CHEI scores were associated with the low mMRC grades. Patients with COPD should be encouraged to maintain a good quality diet to reduce the risk of disease exacerbation.
