A novel explainable online calculator for contrast-induced AKI in diabetics: a multi-centre validation and prospective evaluation study.

Background: In patients undergoing percutaneous coronary intervention (PCI), contrast-induced acute kidney injury (CIAKI) is a frequent complication, especially in diabetics, and is connected with severe mortality and morbidity in the short and long term. Therefore, we aimed to develop a CIAKI predictive model for diabetic patients.

Methods: 3514 patients with diabetes from four hospitals were separated into three cohorts: training, internal validation, and external validation.
