Comparisons of plasma amylin in humans in the absence of diabetes.

Diagnoses	Controls	MCI	Alzheimer's disease
	N = 104	N = 82	N = 26
Median, pM/L	23.5	14.8	17.6
Q1, Q3	13.3, 47.8	8.3, 31.7	7.9, 27.9
p-values	–	0.01	0.05

Median (Q1, Q3) is used to describe the distributions of plasma amylin. Using Wilcoxon rank sum test, the comparisons are shown between a disease subgroup and the controls.
