Comparison of Pulmonary Function Test Before and After SABR

	Baseline			Median test interval after SABR (range)	After SABR			P value
	No. of patient	Median (range)	Mean	Median test interval after SABR (range)	No. of patient	Median (range)	Mean	P value
FEV1	59	71% (14-122%)	67.8%	5.0 months (1.6-16.0 months)	55	66% (12-112%)	66.0%	0.094
DLCO	55	67% (31-135%)	66.3%	5.0 months (1.6-16.0 months)	50	58.5% (14-116%)	60.0%	<0.001

Pre-SABR pulmonary function tests were performed within 3 months before SABR. DLCO was unable to perform on four patients. Post-SABR pulmonary function test results were unknown in three patients, and the test was unable to perform in one patient. Post-SABR DLCO testing was unable to perform in another five patients. Abbreviations: DLCO, carbon monoxide diffusing capacity; FEV1, forced expiratory volume in the first second of expiration; SABR, stereotactic ablation radiotherapy.
