Progression-free (a) and overall (b) survival rates of the groups categorized by mitochondrial superoxide dismutase (SOD2) expression in a cohort of patients with endometriosis-associated ovarian cancer. A high expression of mitochondrial superoxide dismutase (SOD2) was associated with a trend toward a shorter progression-free survival (χ2 = 3.358, p = 0.0669) and was correlated significantly with poor overall survival (χ2 = 4.198, p = 0.0405) in endometriosis-associated ovarian cancers
