The control group is the reference group in the comparisons. The comparisons of counts variables or the numbers at each time point are based on Fisher's exact test for small samples. The comparisons of continue variables are based on t-test to analyze the differences the control and MCI or AD groups. SE: Standard Error; BMI: Body Mass Index; MMSE: Mini-Mental State Exam. P values are shown.
