Lean body mass index and the risk of diabetes onset: A nationwide epidemiological cohort study.
Article in Journal of diabetes investigation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
AIMS/
introductionDiabetes causes microvascular complications and cardiovascular diseases, and identifying its risk factors is a critical issue. Muscle is a primary target organ of insulin; however, previous studies on the relationship between lean body mass and the risk of developing diabetes have reported inconsistent findings. This study aimed to evaluate the association between the predicted lean body mass index (LBMI), which can be easily calculated in daily clinical practice, and the risk of developing diabetes. MATERIALS AND
methodsThis retrospective study analyzed a large scale real-world database to investigate the relationship between LBMI and diabetes risk in both men and women. The incidence of diabetes was determined using ICD-10 codes from an administrative claims database, and Cox regression and cubic spline models were employed.
resultsThe median age (interquartile range) was 59 (45-67) years for men and 63 (50-68) for women. Among 581,176 men and 721,605 women, a lower LBMI was associated with an increased risk of diabetes onset in both men and women (hazard ratio [95% confidence interval] (Men): Q1, 1.27 [1.23-1.32]; Q2, 1.07 [1.04-1.10]; Q3, 1.02 [0.99-1.04]; Q4. 1 [reference value], HR [95% CI] (Women): Q1, 1.10 [1.06-1.15]; Q2, 1.00 [0.97-1.03]; Q3, 0.99 [0.96-1.02]; Q4. 1 [reference value]). The restricted cubic spline regression model revealed that the risk of diabetes onset increased as LBMI decreased in both men and women.
conclusionsWe demonstrated that a lower LBMI was associated with a higher risk of diabetes onset in both men and women.
