With respect to PAF-AH, a statistically significant decrease was found when the EF was compared to the CF in the CF/EF sequence only; the mean decrease in the ln-transformed PAF-AH activity was −0.328 (p = 0.019), which is a 28% decrease in the PAF-AH activity following 8 weeks of treatment with the EF compared to the CF in the CF/EF sequence. Here, PLA2G7 is linked to cystic fibrosis.
