The urinary angiotensinogen-to-creatinine ratio was higher in patients with KDIGO stage 3 AKI and correlated with Scr levels at 3 months (Akin et al., 2023), suggesting that urinary angiotensinogen levels may serve as an indicator of AKI severity, and monitoring its dynamic changes could aid in prognostic assessment and patient management. Here, AGT is linked to acute kidney injury.
