Table 3. Univariate analysis of Cox's regression performed on 44 cases of invasive ductal breast cancer for securin and Ki-67 immunohistochemistry, and MAI.

	P	95% CI	HR
Securin	0.0218	1.1–4.6	2.3
Ki-67	0.1581	0.9–2.1	1.4
MAI	0.0227	1.0–1.5	1.3

MAI=mitotic activity index. The table summarizes P-values with 95% confidence intervals (95% CI) and hazard ratios (HR) of overall breast cancer death.
