Comparison of immunostaining intensities and positive samples (obtained by inmunohistochemical analysis) between groups of breast samples. The labelled cells are classified in three groups according to their intensity range: low (< 10), intermediate (between 10 and 15) and high (>15). Mean ± SD. Values denoted by different superscripts are significantly different from each other. Those values sharing the same superscript are not statistically different from each other. Statistical analysis refers to each antibody separately. Significance was determined by multiple comparisons by the Fisher test at p ≤ 0.05.
