mRNA and protein expression of angiogenetic parameters in IPF and Sarcoidosis. Values are expressed as mean ± SD.

	Sarcoidosis	IPF	P value
VEGF-mRNA	2.99 ± 1.43	18.3 ± 14.9	.036
VEGF-protein	154 ± 36	344 ± 77	.202 (NS)
(pg/mL)
FLT-1-mRNA	204 ± 52	154 ± 33	.434 (NS)
FLT-1protein	3.0 ± 1.4	18.8 ± 6.5	.036
(pg/mL)

NS: Nonsignificant, P <.050 is considered statistically significant
