1 · What the graph read from it

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.

2 · The registry

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 AND

objectivesType 2 diabetes (T2D) stems from metabolic dysregulation, and body cell mass (BCM) comprises the principal physiological substrate of basal metabolic rate (BMR); however, the as-sociation between BCM and diabetes is still unclear. This study examined the relationship of percentage body cell mass (PBCM) with insulin resistance (IR) and T2D, and evaluated the mediators of this association. METHODS AND STUDY

designThis study utilized data from U.S. adults in the National Health and Nutrition Survey (1999-2004). Weighted multivariate regression, restricted cubic spline analysis, subgroup analyses, and sensitivity analysis were employed to investigate the relationship of PBCM with T2D risk biomarkers, IR and T2D. The potential mediating role of body mass index (BMI) was explored.

resultsA total of 2,923 participants aged 18 years or older were included. Preliminary analysis demonstrated an inverse association between PBCM and biomarkers of T2D risk. Further analyses revealed that higher PBCM was associated with lower odds of IR (OR = 0.91, 95% CI: 0.88-0.94, p <0.001) and T2D (OR = 0.89, 95% CI: 0.84-0.94, p <0.001) in the fully adjusted model. Mediation analysis indicated that BMI mediated 70.6% (95% CI: 55.1%-88.9%, p <0.001) of the total effect of PBCM on IR, and 29.9% (95% CI: 14.2%-65.9%, p <0.001) of that on T2D, respectively.

conclusionsPBCM was negatively associated with the prevalence of IR and T2D. Mediation analyses demonstrated a mediating effect of BMI, suggesting that PBCM might be related to IR and T2D, potentially mediated by BMI.
