2. Figure 1
(A) Mitochondrial DNA-to-genomic DNA ratios in cumulus cells from subjects with endometriosis versus controls. Comparison of mitochondrial DNA:genomic DNA ratio for subjects with surgically confirmed endometriosis (n = 11) versus negative controls (n = 39), using nonparametric Kruskal-Wallis test with SAS version 9.3 (median, vs ; difference, +7.51%; P=.2294). (B) Adenosine triphosphate (ATP) levels in cumulus cells from subjects with endometriosis versus controls. Comparison of ATP/total DNA (in attomoles per nanogram) for subjects with surgically confirmed endometriosis (n = 11) versus negative controls (n = 39), using nonparametric Kruskal-Wallis test with SAS version 9.3 (median, vs attomoles/ng; difference, −64.98%; P=.0147).
