Usefulness of Serum Calcium in the Risk Stratification of Midterm Mortality among Patients with Acute Coronary Syndrome

Figure 2

Kaplan–Meier curves comparing survival among serum calcium quantiles in patients with acute coronary syndrome (ACS). The curves of the quartiles of calcium differed significantly (log-rank ), and patients in the lowest calcium quartile had the highest cumulative incidence of mortality.
