Scoring results of IL-8 immunostaining.

IL-8	Leukocytes (median and range)	Glandular epithelium (median and range)
NP (n = 6) resp (n = 4)	0 (0–1)	0 (0–1)
TP (n = 8) resp (n = 5)	0 (0–1)	1 (0–1)
PP (n = 10) resp (n = 10)	2 (1–2) §	2 (1–3) *
C (n = 18) resp (n = 9)	2 (1–3)	2 (1–3)
R (n = 13) resp (n = 2)	2 (1–3)
NR (n = 10) resp (n = 1)	0 (0–3) #

Glandular epithelium (GE) was not present in all samples why the n is less there. In the post term study it was not possible to do statistical calculations of IL-8 immunostaining in GE.

§ = significantly different to NP and TP groups.

* = significantly different to the NP group.

# = significantly different from the C and R groups.
