Association between relative fat mass (RFM) and chronic kidney disease (CKD): data from NHANES 2005-2018.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Relative fat mass (RFM) serves as an emerging metric for estimating body fat composition. This study evaluates the association between RFM and chronic kidney disease (CKD) using data from the National Health and Nutrition Examination Survey (NHANES) covering the years 2005-2018. Descriptive statistics were applied to characterize the study population, and logistic regression models assessed the relationships between body mass index (BMI), waist circumference (WC), RFM, and CKD. To further elucidate the RFM-CKD association, subgroup analyses, restricted cubic spline (RCS) modeling, sensitivity analyses, and mediation analyses were conducted. A positive trend was observed, with higher RFM values correlating with increased CKD risk. Compared to the lowest RFM quartile, individuals in the highest quartile exhibited a significantly elevated CKD risk (OR = 1.82; 95% CI 1.46-2.27; p < 0.001). Mediation analysis identified neutrophil-to-lymphocyte ratio, hemoglobin, glycated hemoglobin, and uric acid as significant mediators in this association, with hemoglobin exerting a potentially protective influence. RFM is associated with CKD, suggesting that attention to RFM may be helpful for CKD research.
