Relationship between cardiometabolic alterations and frailty in Brazilian urban and rural older adults.

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
Background: Frailty is a major public health concern among older adults due to its association with disability, hospitalization, and mortality. Cardiometabolic alterations are prevalent in this population and may be associated with frailty. However, evidence remains limited, particularly across different residential contexts. Objective: Investigate the association between cardiometabolic alterations and pre-frailty and frailty among Brazilian older adults. Methods: This cross-sectional study used data from the baseline survey (2015-2016) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a nationally representative, population-based cohort study. The sample was selected using a multistage, stratified cluster sampling design. A total of 4,368 individuals aged 60 years were included. Frailty was assessed according to the Fried phenotype. Cardiometabolic alterations included diabetes mellitus, hypertension, high cholesterol, excess body weight, abdominal obesity, and cardiovascular risk. Multinomial logistic regression models were used to estimate crude and adjusted odds ratios (OR) and 95% confidence intervals (95% CI). Results: The prevalence of pre-frailty and frailty was 58.3% and 12.3%, respectively. Diabetes mellitus, hypertension, excess body weight, abdominal obesity, and the presence of three or more cardiometabolic alterations were independently associated with higher odds of pre-frailty and frailty after adjustment. A dose-response relationship was observed between the number of cardiometabolic alterations and frailty status. Conclusion: Cardiometabolic alterations are associated with pre-frailty and frailty among Brazilian older adults. The dose-response relationship between the number of alterations and frailty status highlights the relevance of accumulated cardiometabolic burden as a marker of vulnerability to frailty and supports integrated strategies for cardiometabolic risk prevention and management.
