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
Background: Early diabetic kidney disease (DKD) remains difficult to diagnose accurately since microalbuminuria lacks sensitivity and specificity. Tumor necrosis factor receptors (TNFRs), especially TNFR1 and TNFR2, have emerged as potential markers of renal inflammation and injury. Dyslipidemia, particularly reduced high-density lipoprotein cholesterol (HDL), is associated with the inflammatory milieu in type 2 diabetes mellitus (T2DM). Objective: To investigate the association of serum TNFR1 and TNFR2 with early renal injury in T2DM and to determine the impact of HDL on TNFRs levels. Methods: A cross-sectional study was conducted in 258 T2DM patients (135 with normoalbuminuria, 123 with microalbuminuria) and 100 age- and sex-matched healthy controls. Serum TNFR1, TNFR2, lipid profile, fasting blood glucose (FBG), and estimated glomerular filtration rate (eGFR) were measured. Group differences were analyzed, and correlation and multivariable regression analyses were performed to identify determinants of TNFR levels. Results: Both TNFR1 and TNFR2 were significantly higher in patients with microalbuminuria compared with healthy controls ( Conclusion: Serum TNFR1 and TNFR2 are a sensitive biomarker for early renal injury in T2DM. Importantly, low HDL is independently associated with elevated TNFR1 levels, suggesting that lipid metabolism, beyond glucose control, plays a critical role in DKD progression. Monitoring HDL levels and targeting dyslipidemia may aid in the early prevention and intervention of DKD.
