Changes in serum fatty acid levels after treatment with evening primrose oil. (A) In the 160 mg group, all serum fatty acid levels increased, but only the increases in the levels of C18 : 3n (linolenic acid) and C20 : 4 (arachidonic acid) were statistically significant. ^*p=0.006, ^**p=0.006. (B) In the 320 mg group, all serum fatty acid levels increased, but significant differences were only noted in the serum levels of C18:3n (linolenic acid) and C20:4 (arachidonic acid). ^*p=0.001, ^**p=0.000.
