Association of ERRα, β and γ with the indicated steroid hormone receptors and cancer-associated genes in ovarian cancer tissues assessed by means of Spearman’s rank correlation analysis

	ERRα	ERRβ	ERRγ
ERRα		rho = 0.4785 95% CI 0.3457–0.5926 p < 0.0001	rho = 0.3504 95% CI 0.203–0.4823 p < 0.0001
ERRβ	rho = 0.4785 95% CI: 0.3457–0.5926 p < 0.0001		rho = 0.4317 95% CI 0.2944–0.5515 p < 0.0001
ERRγ	rho = 0.3504 95% CI 0.203–0.4823 p < 0.0001	rho = 0.4317 95% CI 0.2944–0.5515 p < 0.0001
ERα	n.s	n.s	rho = 0.2858 95% CI 0.1346–0.424 p < 0.001
CEA	rho = 0.254 95% CI 0.09935–0.3967 p < 0.005	n.s	n.s

Shown are the rank correlation coefficient (rho), the 95% confidence interval (CI) and the p-value, considered as statistically significant in case of p < 0.005 (due to multiple comparison analysis)

Correlations with ERβ, PR, MKI67, TP53, HER2, EGFR, CA-125 and CA72-4 were also tested, but were not statistically significant
