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

Figure 3

Multiple spline regression analyses of log hazard ratios (solid line) and their 95% CIs (dotted line) of midterm mortality associated with serum calcium levels in patients with acute coronary syndrome (ACS). The relationship between serum calcium and midterm mortality was reverse J-shaped.
