Efficacy of Pirfenidone in the Context of Multiple Disease Progression Events in Patients With Idiopathic Pulmonary Fibrosis  Steven D.

2 Figure 1 Disease progression events up to 12 months in patients treated with pirfenidone vs placebo. *Pirfenidone, n = 623; placebo, n = 624. †In this graph, events were treated as independent even if they were recorded on the same calendar date. Dark shaded “caps” on each column depict the percentage of patients who had a second progression event of the same type. 6MWD = 6-min walk distance; %FVC = percent predicted forced vital capacity.

3 Figure 2 A, B, Incidence and sequence of multiple disease progression events up to 12 months in patients treated with pirfenidone vs placebo who had more than one event. Patients were sorted by descending frequency of sequence within total number of events for those who received (A) pirfenidone or (B) placebo in the ASCEND and CAPACITY trials. *Events reported on the same calendar date (joined by + symbol) were treated as a single progression event.
