Best logistic regression models for the sleep status for each subgroup.

aMCI = amnestic MCI, naMCI = non-amnestic MCI, SCD = subjective cognitive decline, MMSE = Mini Mental State Examination, BDI-II = Beck Depression InventoryBest logistic regression models for the sleep status for each subgroup.aMCI即遗忘型轻度认知障碍（amnestic MCI），naMCI即非遗忘型轻度认知障碍（non-amnestic MCI），SCD为主观认知下降（subjective cognitive decline），MMSE为简易精神状态检查表（Mini Mental State Examination），BDI-II为贝克抑郁量表（Beck Depression Inventory）；上述为针对各亚组睡眠状态的最优逻辑回归模型。
