Figure 2. Primary Outcome: Organ Support–Free Days Up to Day 21 in Critically Ill Patients.

A, Distributions of organ support–free days (days alive and free of intensive care unit–based organ support) up to day 21 in critically ill patients. The ordinal scale includes in-hospital death (the worst possible outcome) and the numbers of days alive without organ support. The curves represent the cumulative proportion (y-axis) for each group by day (x-axis), and the bars represent the proportion (y-axis) for each group by day (x-axis). Curves that increase more slowly are more favorable. The difference in the height of the 2 curves at any point represents the difference in the cumulative probability of having a value for days without organ support of less than or equal to that point on the x-axis. B, Organ support–free days as horizontally stacked proportions by intervention group. Red represents worse values and blue represents better values; the deepest red is death and deepest blue is 21 organ support–free days. The primary analysis compared organ support–free days in the control (no antiplatelet therapy) group with the pooled aspirin and P2Y12 inhibitor groups. Accordingly, the distribution of organ support–free days is shown for the pooled antiplatelet group, separate aspirin and P2Y12 inhibitor groups, and control (no antiplatelets) group.
