Comparison of the neuropsychological performance classified into four groups based on regional, global, and striatal cutoffs. In a–d, red squares indicate values higher than the 3rd quartile + 3 × IQR, and blue circles indicate values higher than the 3rd quartile + 1.5 × IQR of a box-and-whisker plot. †p < 0.05 group vs. G(−)R(−). ††p < 0.05 group vs. G(−)R(+). †††p < 0.05 group vs. G(+)Str(−). Abbreviations: ADD, Alzheimer’s disease dementia; aMCI, amnestic mild cognitive impairment; CN, cognitive normal; rdcCL, Centiloid scales of FMM-FBB CTX VOI and regional VOIs; CDR-SOB, Clinical Dementia Rating Scale Sum of Boxes; MMSE, Mini-Mental State Examination; SVLT, Seoul Verbal Learning Test; G(−)R(−), global (−) and regional (−) Aβ rdcCL scales; G(−)R(+), global (−) and regional (+) Aβ rdcCL scales; G(+)Str(−), global (+) and striatal (−) Aβ rdcCL scales; G(+)Str(+), global (+) and striatal (+) Aβ rdcCL scales; IQR, interquartile range
