2. Figure 1
Correlations between interleukin-6 (IL-6), IL-8, and vascular endothelial growth factor (VEGF) concentrations in the peritoneal fluid of patients with endometriosis and revised American Fertility Society endometriosis score (A) and scored grade of pelvic adhesions (B). Spearman correlation coefficients (rs) and their probability levels (P), and the number of cases (N) are shown in the insets.

3. Figure 2
Concentrations of (A) vascular endothelial growth factor A (VEGF-A) and (B) interleukin-6 (IL-6) in the peritoneal fluid of women with endometriosis with and without pelvic adhesions in relation to different grades of the disease. Data are shown as median and 25th to 75th percentile range. Statistical significance of differences were calculated by Mann-Whitney U test. N = number of patients.
