Association of plasma Aβ levels with brain amyloid deposition. A–C Distribution of plasma Aβ40 (A), Aβ42 (B) and Aβ42/Aβ40 (C) levels between Aβ-PET(−) and Aβ-PET(+) groups. Plasma Aβ levels were compared between Aβ-PET(−) and Aβ-PET(+) groups using Mann-Whitney test. ** P < .01; *** P < .001. Horizontal line depicts median and whiskers depict interquartile range. D–F Correlations between Aβ-PET CL and Aβ40 (D), Aβ42 (E) and Aβ42/Aβ40 (F) levels. Solid blue line represents the regression line; dashed lines represent 95% confidence interval. Abbreviations: CL, centiloid
