FIGURE 2.

Effect of inhaled recombinant granulocyte–macrophage colony-stimulating factor (rGM-CSF) on the requirement for unscheduled rescue whole lung lavage (WLL) therapy. Kaplan–Meier analysis shows the percentage of study participants in each group (indicated) who required an unscheduled rescue WLL as a function of time during the 30 months following the scheduled baseline WLL at month 0. The number of participants who had not received an unscheduled rescue WLL at each visit is shown below (number at risk). Significance values (p-values) were determined with the log-rank Mantel–Cox test. ^#: participants who withdrew from the study for personal reasons.
