Pairwise comparisons over time include only those participants with complete information at baseline and at the end of follow up (n = 23). * At the end of follow up, 44 participants provided information about diet, n = 36 plasma serum and diet information, and 30 participants were assessed for anthropometric and other cardiovascular risk factors (Figure S1). Thus, mMDS and PREDIMED included n = 44 for the analysis at the end of follow up and for the comparisons.
