Association of transglutaminase-2 with contrast-induced acute kidney injury in Chinese patients with acute coronary syndrome: a prospective cohort study.
Article in Annals of medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTo investigate the dynamic changes in serum and urinary Transglutaminase-2 (TG2) levels in acute coronary syndrome (ACS) patients and their association with contrast-induced acute kidney injury (CI-AKI), thereby providing novel clinical evidence for risk prediction of CI-AKI.
methodsThis single-center prospective cohort study consecutively enrolled ACS patients hospitalized in the Zhongda Hospital Affiliated to Southeast University, who underwent coronary angiography (CAG) between December 2023 and December 2024. Serum and urinary TG2 levels were measured before and after CAG using enzyme-linked immunosorbent assay. Multivariable logistic regression was performed to identify independent risk factors for CI-AKI, and a predictive model was constructed.
resultsA total of 550 ACS patients were included, of whom 59 (10.7%) developed CI-AKI. Lasso regression analysis further confirmed that the differences between preoperative and postoperative serum TG2 (ΔsTG2) and urinary TG2 (ΔuTG2) were independent risk factors for CI-AKI (both
conclusionIn ACS patients undergoing CAG, elevated serum and urinary TG2 levels and greater peri-procedural changes in these levels are closely associated with the occurrence of CI-AKI. Detecting TG2 levels, particularly their dynamic changes, may serve as an effective biomarker for predicting the risk of CI-AKI.
