Figure 2. Survival and Days Alive, and Free of Organ Support to Day 28.

A, Survival and the proportion of patients without organ support over the first 28 days after randomization. Organ support included mechanical ventilation, vasopressors, and renal replacement therapy. Probabilities are shown for the 441 patients with complete 28-day follow-up.

B, The primary outcome was days alive and free of organ support, including mechanical ventilation, vasopressors, and renal replacement therapy to day 28. Non-White racial groups are plotted together due to small numbers in individual racial groups. The P value for overall between-group difference was derived by t test and the P values for subgroup interaction by analysis of variance.
