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

backgroundChildren with type 1 diabetes mellitus (T1DM) are at increased risk of excess adiposity due to sedentary lifestyle, dietary factors, and insulin therapy. Body mass index (BMI), the most commonly used measure of adiposity, cannot distinguish between fat and lean mass. To address this limitation, alternative indices such as the tri-ponderal mass index (TMI) have been proposed; however, its role in pediatric T1DM remains unclear.

objectiveTo compare body composition between children with T1DM and healthy peers, and to assess the utility of TMI in evaluating adiposity. SUBJECTS AND

methodsThis cross-sectional study included 65 children with T1DM and 65 age- and sex-matched healthy controls. Anthropometric data, waist-to-height ratio (WHR), disease duration, daily insulin dose, insulin regimen, and mean HbA1c values over the previous year were recorded. TMI was calculated as weight (kg)/height³ (m³). Body fat percentage (BFP), fat mass (FM), and fat-free mass (FFM) were assessed using bioelectrical impedance analysis (BIA).

resultsThe median age of children with T1DM was 14.4 (12.2–16.9) years, with a median disease duration of 4.3 (2.6–7.5) years. No significant differences were found between groups regarding SD scores of BMI, WHR, and TMI. Compared with controls, children with T1DM showed significantly higher BFP and BFP SD scores (p = 0.005 and p = 0.002), and elevated FM SD scores (p = 0.01). The FFM/FM ratio did not differ significantly (p = 0.09). Longer disease duration (≥ 5 years) was associated with higher BFP and FM (p < 0.05). TMI correlated positively with BFP (r = 0.66 ), BFP SD score (r = 0.78), FM SD score (r = 0.83), and WHR (r = 0.87), and negatively with the FFM/FM ratio (r = − 0.68) (all p < 0.001).

conclusionChildren with T1DM exhibit higher adiposity than healthy peers, particularly with longer disease duration. TMI showed strong correlations with body fat parameters and may serve as a simple, reliable, and clinically useful tool for assessing adiposity in pediatric T1DM.
