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

backgroundGait is related to weight factors and regulated by the nervous system. Emerging evidence indicates that adiposity impacts brain health. This study explores the relationship between anthropometric indices and gait performance, and investigates the role of brain parameters in the relationship.

methodsThis study included 710 community-dwelling older adults from the Taizhou Imaging Study. Nine anthropometric indices were calculated to assess body weight using standard formulas based on measured height, weight, waist circumference (WC), and hip circumference. Gait assessment includes Timed-Up-and-Go tests, Tinetti tests, and quantitative gait assessment conducted with wearable insole devices. 16 quantitative parameters were summarized into five independent gait domains (rhythm, symmetry, phase, pace and variability) using factor analysis. Quantitative susceptibility mapping was used to measure iron levels in cortical regions.

resultsOverweight/obesity group (body mass index, BMI ≥ 24 kg/m²) had significantly poorer performance in the phase domain (standardized β = -0.172, P = 0.023), specifically manifested in the percentage of the double support time (standardized β = 0.783, P = 0.028) and stance time (standardized β = 0.422, P = 0.019). They also exhibited higher iron levels of the inferior temporal gyrus (ITG) (standardized β = 0.641, P = 0.021). The metabolic-related anthropometric indices have stronger associations with gait performance and indices of abdominal assessment more closely correlated with iron levels. The iron levels of ITG mediated the association of anthropometric indices (BMI, WC, Waist-to-Height Ratio, abdominal volume index and body roundness index) with the phase domain, with mediation proportions ranging from 8.95% to 13.45%.

conclusionIncreased anthropometric indices are associated with relative prolongation of the stance phase and the iron levels of ITG mediates the associations. Our research offers valuable insights into the neuropathological mechanisms underlying of gait abnormalities in the community-dwelling older adults with overweight/obesity.
