Flow of participant selection. A total of 1,772 participants with CU or MCI were recruited for this study. After excluding 36 participants without centiloid data from Aβ PET, the final analyses included 1,736 participants. Participants were sorted into three groups based on their BMI: BMI below 18.5 kg/m2 as underweight, BMI between 18.5 kg/m2 and 24.9 kg/m2 as normal weight group, BMI above 25 kg/m2 as obesity group. Subsequently, participants in each BMI status group were classified into the MH and MU groups according to theInternational Diabetes Foundation definition of metabolic syndrome and previous studies. BMI = body mass index; CU = cognitively unimpaired; MCI = mild cognitive impairment; MH = metabolically healthy; MU = metabolically unhealthy; rdcCL = regional direct comparison centiloid
