Desirability of outcome ranking (DOOR) partial credit scenarios. The top panel provides the partial credit scoring key. Scenario A represents a patient who only places value on surviving (equivalent to a 90-day mortality outcome). Scenario B represents a patient who places more value on quality of life and considers any adverse event as very undesirable. Scenario C represents a patient who places significant value on survival but also tries to balance this with avoiding complications. For each scenario, the difference in mean partial credit scores is calculated by subtracting the mean score for the conventional group from the mean score for the short group. The bottom panel displays contours of the difference in mean partial credit scores. The partial credit score assigned to being alive with 2 or 3 events is combined on the horizontal axis, and the partial credit score assigned to being alive with one event is on the vertical axis. The red line at zero indicates no difference between the mean partial credit scores. Positive differences (shaded in gray) suggest the short course could provide a more desirable outcome, and negative differences (shaded in yellow) suggest the conventional course could provide a more desirable outcome. However, none of the theoretical partial credit scenarios (A–C) demonstrated a significant difference between treatment groups (P > .1 for all scenarios).
