The number of cells showing CD11b or CD14 immunoreactivity in the upper dermis in the Köbner-positive and Köbner-negative groups of psoriatic patients

		Immunopositive cells at different time points (cells/mm2)
		0 d	2 h–1 d	3–7 d
Köbner-positive	CD11b	245 ± 117	386 ± 182	421 ± 130*
	CD14	298 ± 202	315 ± 152	551 ± 125**
		(n = 8)	(n = 8)	(n = 8)
Köbner-negative	CD11b	354 ± 148	433 ± 126	550 ± 245
	CD14	296 ± 103	398 ± 78¶	473 ± 174¶¶
		(n = 10)	(n = 10)	(n = 9)

The results are expressed as the mean ± SD. *P = 0.016 and **P = 0.040 (paired t-test) when comparing the cell numbers in 3–7 d biopsies to those in corresponding 0 d biopsies. ^¶P = 0.006 and ^¶¶P = 0.031 when comparing the cell numbers in 2 h–1 d or in 3–7 d biopsies, respectively, to those in corresponding 0 d biopsies.
