Nonlinear Association Between Body Roundness Index and Axial Spinal Pain in Middle-Aged and Older Chinese Adults: A Nationwide Cross-Sectional 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
backgroundAxial spinal pain is a major cause of disability in middle-aged and older adults. The body roundness index (BRI) reflects central fat distribution, but its association with axial spinal pain is unclear.
methodsWe analyzed cross-sectional data from 10,689 adults aged ≥ 50 years from a national cohort in China. The association between BRI and axial spinal pain was examined using multivariable logistic regression, restricted cubic splines, subgroup analyses, and an evaluation of combined BRI and body mass index (BMI) categories.
resultsHigher BRI was associated with increased odds of axial spinal pain (adjusted OR = 1.05 per unit; 95% CI 1.01-1.08), with the highest quartile showing 22% greater odds than the lowest (OR = 1.22; 95% CI 1.06-1.40). The association was nonlinear (threshold near BRI = 3.0) and modified by drinking status (p interaction = 0.007). The greatest odds were observed in individuals with both high BMI and high BRI (OR = 1.16; 95% CI 1.04-1.30).
conclusionsIn this cross-sectional study, elevated BRI was independently and nonlinearly associated with axial spinal pain, with stronger associations in drinkers and high-BMI individuals. BRI shows promise for community health profiling, though longitudinal studies are needed to establish causality.
