The P values (<0.05), which are statistically significant, are presented in bold. The odds ratios (ORs) (95 % confidence interval (CI)) which correspond to the statistically significant P values are also presented in bold
aPCA-derived Mediterranean dietary pattern with high loadings of vegetables, fruit, legumes and fish, thus closely resembling the Mediterranean diet
bQuartiles of adherence to PCA-derived Mediterranean dietary pattern, with subjects in quartile 1, showing the lowest consumption of vegetables, fruit, legumes and fish, and thus, lowest adherence to this dietary pattern and with subjects in quartile 4, showing the highest consumption of the same four food groups and therefore highest adherence to this dietary pattern
cAdjusted for menopausal status, age and for the other PCA-derived dietary components (Pattern 1, 2 and 3)
d P for trend within a specific SNP genotype across quartiles of adherence to the PCA-derived Mediterranean dietary pattern
