*MD score (Trichopoulou et al.)18.
Continuous variables were presented as means (±SD) or medians [25th-75th percentiles (Pc)]. Differences in variables across tertiles of MD adherence were tested using ANOVA test. Same superscripts in different columns denote non-significant differences while different superscript letters denote statistically significant differences in a paired comparison (after multiple comparison post-hoc Bonferroni test).
