Table 4. General Linear Regression Analyses of the Association of Plasma Amylin Concentration With Brain Volumea.
Plasma Amylin Concentration | Temporal Lobe Brain Gray Matter Volume, %b | Logarithm of White Matter Hyperintensities, %b | ||
---|---|---|---|---|
β Estimate (SE) | P Valuec | β Estimate (SE) | P Valuec | |
Highd | 0.17 (0.05) | <.001 | −1.85 (0.70) | .008 |
Extremely highe | 0.02 (0.07) | .82 | 0.63 (1.09) | .57 |
The models were adjusted for age, sex, education, smoking, body mass index, diabetes, cardiovascular diseases, APOE4, and high-density lipoprotein. Low plasma amylin concentration (<75 pmol/L) was used as the reference.
Given as a percentage of total cerebral brain volume.
P values adjusted using conventional Bonferroni correction (P < .004).
75 pmol/L to less than 2800 pmol/L.
2800 pmol/L or greater.
