Differentially-expressed genes that distinguish severe IPF from control.

†<p>Significance analysis of microarrays (SAM) of IPF samples when categorized by percent predicted D_LCO ≤35% [N = 15]. Differentially- expressed transcripts with <1% false discovery rate and ≥ 2-fold change in expression are represented. Fold changes are expressed as log₂ ratio. See supplementary tables for a complete list of differentially-expressed genes and corresponding accession numbers.
