Exhaled breath condensate (EBC) LPA levels. Levels of docosatetraenoyl (22:4) LPA (A) and total LPA (B) in the exhaled breath condensate (EBC) of IPF patients and controls, as determined by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Levels of 22:4 LPA, but not total LPA, were significantly higher in IPF patients vs. controls, with minimal overlap in EBC 22:4 LPA levels between the two groups. *p = 0.001 for the comparison of IPF vs. controls by Mann Whitney test.
