Healthy diet is associated with better lung function, especially in individuals with COPD: findings from the Lifelines cohort study.

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
Objective: To investigate whether the association between diet and lung function (LF) differs according to asthma or COPD status in the Lifelines cohort study. Methods: We included adults from Lifelines with valid dietary and spirometry data. Dietary quality was calculated at baseline using the Lifelines diet score (LLDS) (range 0-48, where higher scores indicate a healthier diet). LF was assessed Results: Higher LLDS was associated with higher LF and slower decline. In cross-sectional analyses (n=83 460, 59% female, mean age 44±13 years), higher LLDS was associated with higher FEV Conclusions: Higher diet quality was associated with better LF, particularly in those with asthma or COPD, and with slower decline in participants with COPD. These findings suggest that diet may be a modifiable factor in respiratory health.
