The relationship between the total volume of the hippocampus and age in met and non-met carriers. Using a polynomial fitting curve, we found a significant correlation (r = −0.447, P = 0.0150) between age and the volume of the hippocampus in met carriers. No such correlation was found in non-met carriers (r = −0.178, P = 0.2639). Furthermore, the slope of the regression in the hippocampal volume of met carriers (slope = −0.038) was twice the value of the slope of regression in non-met carriers (slope = −0.016; Published from Sanchez et al., 2011).
