Kaplan–Meier estimates of two-year survival by baseline plasma S100A12 levels. The median value of plasma S100A12 levels of all participants at baseline were 18.79 ng/mL. The participants were divided into a lower S100A12 group (solid line) and a higher S100A12 group (dotted line) according to this median value (χ2 = 10.239, P = 0.001 by the log-rank test).
