Association of adherence to a Mediterranean-type diet (MTD) at baseline. The boxplot displays the mean value of frailty index (FI) for subjects with low (MTD ≤ 3), medium (MTD 4–5), and high (MTD ≥ 6) adherence to a MTD. Significant differences were observed between low and high adherence group (p = 0.0322).
