The Dietary Inflammatory Index (DII) and COPD: A Cross-Sectional Study from the NHANES.
Article in International journal of chronic obstructive pulmonary disease, 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
Background: While diet may impact the risk of chronic obstructive pulmonary disease (COPD), the relationship between COPD and dietary inflammatory potential remains largely unexplored. This study aimed to evaluate the association between COPD status and the dietary inflammatory index (DII). Methods: Utilizing NHANES data from 2013 to 2018, the study investigated the relationship between Dietary Inflammatory Index (DII) scores, derived from 24-hour dietary recall interviews, and COPD status. Weighted logistic regression and restricted cubic spline (RCS) analyses were employed to assess this association. Additionally, stratified and interaction analyses were conducted to evaluate the consistency of the relationship and identify potential modifiers. Results: Individuals diagnosed with COPD demonstrated significantly elevated DII scores in comparison to those without COPD. An increment of one unit in the DII was correlated with an increased risk of developing COPD, as indicated by an odds ratio (OR) of 1.05 (95% CI:1.09, 1.21; Conclusion: The study results imply that consuming a pro-inflammatory diet is connected to a greater chance of developing COPD among US residents. Dietary strategies aimed at reducing inflammation might help in preventing COPD and associated illnesses.
