PGR and neoplasm: In addition, no significant correlation was found between the expression of SIRT3 and tumor stage (OR = 1.68, 95% CI = 0.85–3.25, P = 0.12), tumor size (OR = 0.85, 95% CI = 0.60–1.22, P = 0.38), gender (OR = 1.06, 95% CI = 0.79–1.41, P = 0.71), estrogen receptor (ER) (OR = 1.92, 95% CI = 0.95–3.90, P = 0.07) and progesterone receptor (PR) (OR = 0.95, 95% CI = 0.22–4.10, P = 0.95) in total or subgroup analyses (Table 2).
