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
Recent interest in metabolically healthy obesity highlights the need to evaluate the relationship between adiposity and hematologic and metabolic biomarkers. With the increasing use of bioelectrical impedance analysis (BIA), measuring body composition, including percent body fat (PBF), has become more accessible. This study aimed to investigate the associations between PBF and hematologic and metabolic biomarkers related to cardiometabolic health. We conducted a retrospective, cross-sectional analysis using data from the 2023 Korea National Health and Nutrition Examination Survey (KNHANES-IX), which included BIA-based body composition metrics. A total of 5,518 adults with complete records and no predefined outliers were analyzed. Survey-weighted Pearson correlation coefficients were calculated by sex and age groups, followed by multiple linear regression adjusting for sex, age, and body weight. PBF was significantly associated with alanine transaminase (β = 1.06 per % PBF), hemoglobin (β = 0.02), hematocrit (β = 0.06), total cholesterol (β = 0.48), high-density lipoprotein cholesterol (β = -0.50), low-density lipoprotein cholesterol (β = 0.62), and triglyceride (β = 2.93). No significant association was found between PBF and aspartate transaminase. Notably, the associations of PBF with alanine transaminase and triglycerides varied by sex and age group. These findings suggest that PBF may be a useful non-invasive marker for assessing cardiometabolic risk, warranting further investigation in diverse populations.
