		The original linear regression method
		Mean of cycles 1–3	Mean of cycles 3–7	Minimum	The taking-difference linear regression method
Amplification efficiency	Overall values	Middle	Largest	Smallest	Middle
	Values >100%	Never	Sometimes	Never	Never
	Change from 100% to 60% amplification mix	Not monotonically decreasing	Not monotonically decreasing	Not monotonically decreasing	Monotonically decreasing
	SD	0.037	0.035	0.061	0.023
Initial DNA amount	RE	Large (up to ∼30%)	Small	Large (up to 300%)	Small
