Abbreviations: r, correlation factor; EC, endometrial cancer; BMI, body mass index; IL, interleukin; TNF, tumor necrosis factor; ROS, reactive oxygen species; GPx, glutathione peroxidase; SOD, superoxide dismutase. p-value was calculated by Pearson’s or Spearman’s correlation analysis and was considered significant if it was less than 0.05 (bold value).
