Interim PFT analysis showed no difference in route of administration.

PFTs were performed at follow-up visits over a 2-year period.

We did not find a significantly different effect on the PFTs after segmentectomy or lobectomy.

There was no significant correlation between symptomatic score or PFT and ILD score or PnE.

Two to four weeks after implementation of the new PD regimen, a second PFT was performed.
