ANOVA indicates the p values associated with an ANOVA analysis.
Post hoc indicates the pairwise analysis results (p values) following Tukey’s analysis between age groups (3, 9, and 36 months).
Symbols represent significant difference:
*
significant difference from 9 months
^
from 36 months, and
+
from 3 months.
