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
backgroundMore information is required where the relation of diabetic neuropathy and body composition through bioimpedance is addressed. Therefore the aim of this study was to investigate the association between peripheral (PN) and autonomic neuropathy (AN) with bioimpedance in patients with type 2 diabetes mellitus (T2DM) aged 18 to 64 years.
methodsA cross-sectional study was conducted at a private hospital in Northeastern Mexico between November 2023 and March 2024. Patients with T2DM were evaluated using the Michigan Neuropathy Screening Instrument (MNSI) for PN, Sudoscan for AN, and bioimpedance analysis (InBody) for body composition. Other variables considered included diabetes duration, hemoglobin A1C (HbA1C), and lipid profile. Chi-square, T-test, and Wilcoxon tests were used for independent variables, Cohen's kappa for concordance, and logistic regression models for association analyses.
resultsA total of 160 patients were analyzed, with a median (IQR) age of 51 (12) years, and a majority being male (n = 81, 51%). The prevalence of PN was 30% (n = 48) and AN was 35.6% (n = 57), with a Cohen's kappa concordance of 0.282. Patients with PN had higher median (IQR) visceral fat mass [20 (8.3) vs. 17 (10.3) kg, p = 0.010], arm fat mass [3.65 (3.35) vs. 2.70 (2.30) kg, p = 0.004], torso fat percentage [485 (166) vs. 369 (173), p < 0.001], arm circumference [40.1 (7.4) vs. 36.4 (5.7) cm, p < 0.001], arm muscle circumference [32.1 (3.8) vs. 30.7 (4.7) cm, p = 0.008], and skeletal muscle index (SMI) [8.35 (1.25) vs. 7.95 (1.55), p = 0.009]. For AN, a higher torso muscle percentage was observed [105.2 (6.2) vs. 103.3 (7), p = 0.02]. No significant differences were found in HbA1C or lipid profile. Logistic regression for PN showed associations with T2DM duration (OR = 1.111, p = 0.006), age (OR = 1.080, p = 0.004), leg fat mass (OR = 187.197, p = 0.003), and SMI (OR = 0.612, p = 0.021), with a Nagelkerke R² of 0.328. No significant predictors were found for AN.
conclusionA high prevalence of neuropathy was observed, with a significant association between body composition and PN, highlighting greater adiposity in limbs, torso, and visceral fat, as well as age, T2DM duration, and SMI.
