The association between the BRI and all-cause and cardiovascular mortality in COPD patients.
Article in BMC pulmonary medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveWaist circumference (WC) has been linked to exacerbations in chronic obstructive pulmonary disease (COPD), but the relationship between WC, height, and the Body Roundness Index (BRI) with mortality in COPD patients remains unclear. This study investigates the association between BRI and both all-cause and cardiovascular mortality in COPD patients.
methodsData from 3,672 COPD participants (1,517 men and 2,155 women; mean age: 53.17 ± 16.46 years) were obtained from NHANES (1999-2018). Multivariable Cox proportional hazards models, Kaplan-Meier analysis, Nelson-Aalen cumulative hazard plots, and restricted cubic spline analyses were used to assess the relationship between BRI and mortality. ROC curves were constructed to evaluate BRI's predictive performance. Subgroup and sensitivity analyses ensured robustness of the models.
resultsThe BRI was associated with all-cause (HR: 1.12, 95% CI: 1.05-1.19) and cardiovascular mortality (HR: 1.14, 95% CI: 1.01-1.29). Kaplan-Meier curves and Nelson-Aalen plots demonstrated that higher BRI quartiles correlated with lower survival probabilities and increased cumulative mortality incidence. ROC curve analysis showed that BRI outperformed other models in predicting all-cause [AUC: 0.81 (0.79-0.82)] and cardiovascular mortality [AUC: 0.79 (0.76-0.81)]. A significant interaction was observed between BRI and alcohol consumption for all-cause mortality. Results remained consistent after excluding participants who died within two years (HR: 1.10, 95% CI: 1.03-1.18) and in the alcohol-consuming subgroup (HR: 1.14, 95% CI: 1.05-1.24).
conclusionThe BRI is associated with increased all-cause and cardiovascular mortality in COPD patients, with higher BRI quartiles linked to greater mortality risk. Targeting BRI may offer a potential strategy to reduce mortality in this population.
