Determining the cutoff threshold of the expression of CD71 on neutrophils based on the metastatic spread using the two-tailed minimal p-value approach (chi-square test; n = 70).

MFI CD71 (%)	p-value (chi-sqare test)	CD71 Expression	N	Probability of metastasis (%)
200	0.14	Low	5	0
		High	65	44.4
250	0.05	Low	14	7.1
		High	56	34.0
300	< 0.01	Low	26	3.8
		High	44	43.2
350	< 0.01	Low	35	8.6
		High	35	48.6
400	< 0.01	Low	42	16.7
		High	28	46.4
450	0.19	Low	53	24.5
		High	17	41.2
500	0.26	Low	61	26.2
		High	9	44.4

The optimal cutoff value with the lowest p-value and the highest probability of metastatic spread is highlighted in bold.
