Table 2.

Rank correlation coefficients and partial rank correlation coefficients between average D and ADC values for both readers on the one side, and PMN density on the other.

	Rank correlation coefficients		Partial rank correlation coefficients (adjusted for histopathological grading and tumor cell-stroma-ratio)
	CD15-positive cells	azurocidin-positive cells	CD15-positive cells	azurocidin-positive cells
D	-0.723	-0.703	-0.713	-0.692
ADCall	-0.601	-0.625	-0.596	-0.623
ADC800	-0.616	-0.605	-0.616	-0.607

All coefficients shown in Table 2 were significantly different from zero (p < 0.05).
