a For each cholesteryl ester the fatty acid residue esterified to cholesterol is given. One-tailed significance was calculated with log10 (1+ [CE concentration as pmol per 1 RFU Nile red]) testing whether the individual CEs are elevated in CF compared to Non-CF. CL: cholesteryl linoleate; CA: cholesteryl arachidonate. P-values indicating statistical significance are shown in bold.
