1 · What the graph read from it

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.

2 · The registry

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

The Body Rounds Index (BRI) is an anthropometric indicator specifically developed to evaluate an individual's obesity level, particularly emphasizing central or abdominal obesity. This study aimed to explore the relationship between BRI and all-cause mortality in older U.S. adults. The research sample comprised individuals aged 65 and older from the National Health and Nutrition Examination Survey (NHANES), eligible for mortality analyses between 1999 and 2018. We utilized Cox regression analyses, restricted cubic spline (RCS), threshold effects analysis, Kaplan-Meier curves, and subgroup analyses were conducted to assess how the BRI correlates with all-cause mortality among older adults in the U.S. To further ensure the robustness of our findings, we conducted sensitivity analyses. Among 5371 U.S. older adults (age ≥ 65), with an average age of 72.45 (standard deviation [SD]:5.65) years, 2884 (60%) were women. During the follow-up period, there were 2781 deaths from all causes among the 5371 participants. After adjusting for all covariates, a U-shaped association was identified between BRI and the all cause mortality. Compared to a BRI of less than 4.457, a BRI between 4.457 and 5.538 was associated with a 19% reduction in the likelihood of mortality from any cause (HR = 0.81, 95% CI = 0.69-0.95). A BRI between 5.538 and 6.888 was linked to a 8% reduction in mortality risk (HR = 0.92, 95% CI = 0.79-1.07), while a BRI exceeding 6.888 showed a 1% increase in this risk (HR = 1.01, 95% CI = 0.87-1.17). RCS analysis indicated a U-shaped relationship between BRI and all-cause mortality. The turning point was located at 4.546, with correlations observed both before and after this point. This NHANES-based study highlights the U-shaped relationship between BRI and all-cause mortality among U.S. older adults, suggesting that the BRI has predictive value for mortality outcomes. The findings offer compelling support for utilizing BRI as a non-invasive mortality risk screening tool.
