IL13 and asthma: Similarly, in patients with mild asthma, there were significant increases in median concentrations of the type 2 cytokines IL-5 (median, 0.13 pg/mL; IQR, 0.05-0.19 pg/mL) compared with those in healthy subjects (0.003 pg/mL; IQR, 0.001-0.006 pg/mL; P < .001) and IL-13 (0.009 pg/mL; IQR, 0.0009-0.026 pg/mL) compared with those in healthy subjects (0 pg/mL [IQR, 0-0.0008 pg/mL]; P < .05) in BAL fluid (see Fig E4 in this article's Online Repository at www.jacionline.org).
