Figure 2.

The Kaplan-Meier survival rate analysis of the 30-day cumulative survival of traumatized limbs associated with open fractures and shock. (A) Significantly lower incidence of limb salvage in extremities with an open fracture (red dashed line) than in those without an open fracture (blue dashed line) is demonstrated. (B) Patients with an initial shock status (red dashed line) lose their limbs more rapidly than those without (blue dashed line). The associated confidence interval (CI) is plotted in a continuous line with the same color as the risk factor.
