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
backgroundType 2 diabetes mellitus (T2DM) is frequently associated with diabetic kidney disease (DKD) and chronic heart failure (CHF), conditions that share overlapping pathophysiological mechanisms. Adropin, a liver- and brain-derived peptide hormone, has emerged as a novel biomarker involved in metabolic regulation, endothelial function, and inflammation. However, its role in differentiating stages of T2DM-related complications remains underexplored.
objectivesThis study aimed to evaluate serum adropin levels in T2DM patients with and without DKD and to assess its association with coexisting CHF.
methodsThis was an observational case-control study which was conducted over a period of one year and included 111 participants divided into three groups: healthy controls, T2DM without nephropathy, and T2DM with nephropathy (with and without CHF). Serum adropin levels were measured using enzyme-linked immunosorbent assay (ELISA), and comprehensive clinical, biochemical, and echocardiographic assessments were done.
resultsSerum adropin levels were significantly reduced in T2DM patients (0.61 ± 0.13 ng/mL, p < 0.0001), with the lowest levels observed in those with both DKD and CHF (0.47 ± 0.12 ng/mL, p < 0.0001) compared to controls (0.76 ± 0.10 ng/mL, p < 0.0001). A progressive decline in adropin was noted with worsening glycemic control, renal dysfunction, chronic inflammation, and cardiac dysfunction. Significant inverse correlations were found between adropin and glycosylated hemoglobin (HbA1c) (
conclusionThe study demonstrated that serum adropin levels decline progressively with worsening cardiorenal-metabolic parameters. These findings reinforce the role of adropin as a sensitive marker of endothelial and metabolic dysfunction, especially in patients with coexisting T2DM, DKD, and CHF. Given its strong correlation with markers of glycemic control, renal impairment, and inflammation, adropin may serve as a noninvasive biomarker for early detection and risk stratification.
