Table 1 Univariate and multivariate analysis of potential prognostic variables

From: The H3K9 methyltransferase G9a is a marker of aggressive ovarian cancer that promotes peritoneal metastasis

Parameters Comparison Univariate analysis Multivariate analysis
   HR (95% CI) P-value HR (95% CI) P-value
G9a score Low (0, 1); High (2, 3) 1.80 (1.16 to 2.77) 0.009* 1.42 (0.84 to 2.40) 0.196
FIGO stage pT1-pT2; pT3-pT4 4.72 (2.73 to 8.15) <0.0001* 2.57 (1.27 to 5.22) 0.009*
Histological grade G1; G2; G3 1.72 (1.14 to 2.60) 0.010* 1.32 (0.85 to 2.04) 0.214
Histological subtype Serous; Non-serous 1.71 (1.11 to 2.63) 0.016* 0.89 (0.48 to 1.66) 0.729
