Inconsistencies in lowercase letters a, b, c in the table indicate significant differences, and inconsistencies in uppercase letters A, B, C indicate significant differences

Group A was the cell control group, group C was the chlorogenic acid control group, group D was the virus control group, and group F was the chlorogenic acid intervention group
