Table 2. Summary of lead times of PD detection prior to evaluation of PD by imaging modalities.

Patient number	Lead time prior to PD by imaging (months)
	Molecular PD	Early detection model PD	MR model PD
P1	1.33	8.00	2.67
P2	2.80	2.80	NA
P3	2.67	1.33	NA
P4	1.00	1.00	1.00
P5	ND	1.40	1.40
P6	1.43	1.43	5.63
P7	ND	ND	5.57
P8	ND	5.30	1.40

PD, disease progression; ND, not detected in samples; NA, not applicable/not computed due to lack of tissue sample.
