Summary of ddPCR MRD Results by Each Task (1.5 μg DNA Was Used).

		Time Point	RQ-PCR	ddPCR POS-Q, % (n/N)	ddPCR POS-NQ, % (n/N)	ddPCR NEG, % (n/N)
Task 1	POS ≥ 5 × 10–4 +33;POS-NQ +78	+78	45 POS-NQ	29 (13/45)	35.5 (16/45)	35.5 (16/45)
Task 2	POS ≥ 5 × 10–4 +33;NEG +78	+78	79 NEG	6.3 (5/79)	21.5 (17/79)	72.2 (57/79)
Task 3	POS-NQ +33	+33	33 POS-NQ	6 (2/33)	27.3 (9/33)	66.7 (22/33)
Task 4	NEG +33	+33	52 NEG	0	9.6 (5/52)	90.4 (47/52)

ddPCR = droplet digital polymerase chain reaction; MRD = minimal residual disease; NEG = negative; POS = positive; POS-NQ = POS not-quantifiable; POS-Q = POS quantifiable; RQ-PCR = real-time quantitative polymerase chain reaction.
