FIGURE 2.

Levels of docosanoids in the BAL fluids of healthy and COVID‐19 patients. BALs were obtained and processed as described in Methods. Lipids then were extracted and quantitated by LC‐MS/MS. A, Docosanoid biosynthetic pathways. B, Levels of docosapentaenoic acid n‐3 (DPAn‐3) and docosahexaenoic acid (DHA). C,D, Docosanoid levels. E, Proportions of the different docosanoids from panel C and D. Results are from the BALs from 25 healthy subjects and 33 COVID‐19 patients. P values were obtained by performing a Mann‐Whitney test using the GraphPad Prism 9 software: * = P < .05, ** = P < .01, *** = P < .001, **** = P < .0001
