TABLE 2.

Differential analysis of TC, TCHO, and ALT in different age groups. Significant differences existed in TG and TCHO in different age groups (P < 0.05), but there were no statistical differences in ALT between four groups (P > 0.05) (a, b, c, and d are used to represent the statistical difference between groups with the same superscript letter).
