Duration of septic shock. Kaplan–Meier survival curves showing durations of septic shock for the matched cohort. The time to event period was defined as the duration from onset of septic shock until resolution of shock. Patients who died before resolution of refractory septic shock occurred were right-censored, and censored cases are marked with vertical bars.
