Figure 1 Survival curve for the 50 PGE1-treated patients and 50 placebo-treated patients. Survival days are counted from the start of infusion. The + indicates the last date of contact for individual patients—they are counted as survivors.

Figure 2 Mean change of systemic vascular resistance index from baseline (study day 0.). In this and subsequent figures, PGE1 (•) or placebo (○) was infused for 7 days or until the patient died. The reading on study day 0 is just prior to the start of infusion and on study day 8 is a post-infusion value. The abscissa is the mean change from baseline for all patients surviving that day. Vertical bars represent standard error of the mean. CHEST 1989 96, 114-119DOI: (10.1378/chest.96.1.114) Copyright © 1989 The American College of Chest Physicians Terms and Conditions
Figure 3 Mean change of mean arterial pressure from baseline. In this and subsequent figures* = p<0.05 and ** = p<0.01 between the two treatment groups. PGE1 (•) or placebo (○), as in Figure 2.
