Association between dietary intake of live microbes and chronic obstructive pulmonary disease: a cross-sectional study of NHANES 2007-2012.
Article in BMC pulmonary medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT00005154 (National Health and Nutrition Examination Survey IV), which is not on this map. Cited by 1 paper.
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.

Abstract
backgroundDiet plays a crucial role in intervening in the development of chronic obstructive pulmonary disease (COPD), yet previous studies have not investigated the impact of dietary intake of live microbes on COPD. This study aims to assess the relationship between the two.
methodsParticipants from the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2012 were selected. The exposure variable was the estimated intake of live microbes in the diet, categorized into low, medium, and high groups. The outcome variable was COPD. A multivariable logistic regression model was used to assess the relationship between estimated dietary intake of live microbes and the risk of COPD.
resultsIn the fully adjusted multiple logistic regression model, participants with moderate and high dietary intake of live microbes showed a negative association with the prevalence of COPD compared to those with low estimated intake, with reductions of 38% (OR, 0.62; 95% CI: 0.39-0.99, P < 0.05) and 44% (OR, 0.56; 95% CI: 0.34-0.92, P < 0.05) respectively. Additionally, subgroup analysis results remained stable with no observed interactions.
conclusionOur study suggests a negative association between higher dietary live microbe intake and the risk of COPD among adults in the United States.
