Coordinated Increased Expression of Cyclooxygenase2 and Nuclear Factor 𝜅B Is a Steady Feature of Urinary Bladder Carcinogenesis

Table 4

Coexpression of COX-2 and NF𝜅B of cytoplasmic (C) and nuclear (N). Positive correlation was established between expression of COX-2 and nuclear staining of NF𝜅B during progression of carcinogenesis.

Expression	Spearman correlation coefficient (𝑃 value)	Cochran-Armitage Test for trend 𝑃 value
NF𝜅B (N) versus COX-2	0.11 (.208)	.160
NF𝜅B (C) versus COX-2	−0.01 (.900)	.920
