Infiltration density of CD68⁺ mononuclear cells in a total of 17 cases ranged from score 1–3; n=4 cases CD68⁺ score 1 (low), n=6 cases CD68⁺ score 2 (moderate) (for uPAR one case with CD68 score 2 was not available) and n=7 cases CD68⁺ score 3 (high) (for uPAR one case with CD68 score 3 was not available). The infiltration density of CD68⁺ mononuclear cells and the expression of uPAR, HER-2 and MMP-9 in tumor cells all denoted as score 0–3 of positive breast carcinoma cells; 0 = negative, 1 = low, 2 = medium and 3 = high. Each case is represented by a dot and the median value of each group is indicated by a line. The Jonckheere-Terpstra test was used to determine significant associations between increasing levels of CD68⁺ cells and increasing tumor cell expression of uPAR, HER-2 or MMP9 (^*p<0.05, ^**p<0.01, ^***p<0.001).
