Association between red blood cell distribution width-to-albumin ratio and risk of low lean mass: A cross-sectional study of NHANES 1999-2018.

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
ObjectivesLow lean mass (LLM), as a critical element of sarcopenia, is associated with chronic inflammation and malnutrition and presents substantial risks to ageing populations. Although the red blood cell distribution width-to-albumin ratio (RAR) has been identified as a promising biomarker in various inflammatory and nutritional contexts, its relationship with LLM has not yet been investigated. This study seeks to examine the association between RAR and the risk of LLM.MethodsA cross-sectional analysis was conducted using data from 22,299 adults participating in the National Health and Nutrition Examination Survey (NHANES) from 1999 to 2018. LLM was defined according to the criteria established by the Foundation for the National Institutes of Health. Multivariable logistic regression and restricted cubic spline models were employed to assess the relationship between RAR and LLM, adjusting for variables including age, gender, marital status, race and ethnicity, body mass index, smoking status, alcohol consumption, educational attainment, diabetes mellitus, cardiovascular disease, moderate-to-vigorous physical activity, and time spent in sedentary activities. Subgroup analyses and propensity score matching analyses were also conducted.ResultsThe prevalence of LLM was 10.3% in NHANES 1999-2018. Restricted cubic splines analysis revealed a significant dose-response relationship between RAR and LLM risk (
