Analysis of this small exploratory dataset showed no statistical significance towards increased numbers of CD68+ cells (one-way ANOVA with Tukey’s multiple comparisons test, 1.1 ± 0.5% vs. 0.9 ± 0.9% vs. 1.8 ± 1.3%) and collagen-rich area (one-way ANOVA with Tukey’s multiple comparisons test, 45.8 ± 4.5% vs. 52.4 ± 1.9% vs. 53.1 ± 7.1%), when comparing endometriosis patients without pain symptoms (Group 2) versus endometriosis patients with only DYSM (Group 3) and endometriosis patients with both DYSM and CPP (Group 4). This evidence concerns the gene CD68 and endometriosis.
