A comparison of the data between the AICS plaque group and the AICS non-plaque group showed that the levels of IgE and Lp-PLA2 in the AICS plaque group were higher than those in the AICS non-plaque group and the TIA group, and the differences were statistically significant (p < 0.05). Here, PLA2G7 is linked to transient ischemic attack.
