Fig 4. Kaplan-Meier survival curves stratified by three groups, UIP without emphysema, UIP with emphysema and SRIF.

The highest survival rate was observed for patients with SRIF (mean survival: 8.79 ± 0.78 years), and this was significantly higher than survival in UIP with emphysema (median survival: 4.10 ± 1.96 years, p = 0.035) and UIP without emphysema (median survival: 2.95 ± 1.06 years, p = 0.026).
