Proliferative Activity in Libyan Breast Cancer with Comparison to European and Central African Patients

Table 5

Univariate analysis on the significance of the most important prognosticators in the whole Libyan material using cut points at 19 and 44 mitotic figures/mm² and 15 and 58 mitotic figures/10 hpfs for SMI and MAI, respectively. Different subgroups of the whole material are also tested in the corresponding method.
