FIGURE 1.
Survival without CKD in patients with IM with low risk (LR) or high risk (HR) based on the prognostic score of CKD. For a given patient, the prognostic score is calculated using the following formulas: Score = 0.068 * Patient age at IM diagnosis − -0.88 * Sex + 2.4 * History of cardiovascular event (with Sex = 1 if the patient is a women and = 0 if a man, and History of cardiovascular event = 1 if the patient has history of cardiovascular event and = 0 if not). Low risk was defined by a score <1.80, and high risk by a score ≥1.80.
