3 Figure 2 Handheld FEV1 versus Laboratory FEV1 at baseline, day 80, and 1 year for the total cohort and subset 1. Relationship of FEV1 measurements between handheld spirometry (X-axis) and laboratory PFT (Y-axis), with line of regression (___), 95% confidence intervals (---), and line of equality (…) which indicates perfect agreement.
