All values are expressed as mean ? SD. Difference of means between groups
were analyzed by Student’s t test or analysis of variance (ANOVA), followed bythe
Bonferroni collection for multiple comparisons, depending on the number of
groups. We performed correlation analyses between changes in different pa-
rameters during the intervention using Spearman’s coefficients. There were only
two visits for blood tests: at baseline and at the end of 3 mo. Significance of
changes during the intervention was determined by comparing the changes
between baseline and end of study within each group by paired t test, and by
comparing the differences among means of the three groups at the end of the

study by ANOVA. We also performed a two-way ANOVA with factors for group
and time. Linear regression analysis was used to examine the effect of dietary
AGE intake on several parameters in a model including weight change. First, we
determined the association between study group and each one of the other
biochemical/metabolic parameters (CML, MG); then we added weight change to
the model and determined the effect on the association.
All analyses were performed using SPSS 20.0 software (SPSS, Chicago, IL,
USA). Significance was defined as a value of P < 0.05 and based on two-sided
tests.
