Figure 1From: Long-term survival and healthcare utilization outcomes attributable to sepsis and pneumonia Kaplan-Meier survival functions of three patient cohorts. An overall log-rank test showed that the survivor functions differed across patient cohorts (p < 0.01); the survival of the no-infection group was longer than that of the sepsis group (p < 0.01) and the pneumonia group (p < 0.01).Back to article page
