Table 2.

Average annual rate of changes in lung function.

Average annual rate of change 95% CI
FVC (mL/year) − 102 − 116, − 87
FVC (% of predicted/year) − 2.2 − 2.7, − 1.6
DLCO (mL/mmHg/min/year) − 0.9 − 1.0, − 0.8
DLCO (% of predicted/year) − 3.9 − 4.5, − 3.2

CI confidence interval, FVC forced vital capacity, DLCO diffusing capacity of the lung for carbon monoxide.
