ARISE Investigators and the ANZICS Clinical Trials Group. N Engl J Med. 2014 Oct 16;371(16):1496-506
ARISE was a multicenter, international ED unblinded RCT that found no difference in all-cause 90 day mortality (ARR 0.3%, NNT 352), and no difference in multiple clinically-important secondary outcomes, between modern day non-protocolized septic shock management and the Early Goal Directed Therapy (EGDT) protocol. In conjunction with ProCESS, this is a landmark study emphasizing that the key components of the EGDT protocol to optimize septic shock management are early recognition, early antibiotics, and optimal fluid resuscitation.

Survival analyses are used in clinical trials that follow patients over time for primary outcomes such as death, relapse, adverse drug reaction, or development of a new disease. The follow-up time may range from hours to years and a different set of statistical procedures are employed to analyze the data. Terms frequently seen in papers with survival analyses include Cox proportional hazard model, hazard ratio, Kaplan-Meir curve.
