Fig. 4From: A novel extrachromosomal circular DNA related genes signature for overall survival prediction in patients with ovarian cancerUnivariate Cox regression analysis of amplified genes in OV associated with prognosis. A Hazard ratio and P-value of constituents involved in Univariate Cox regression and some parameters of the eccDNA signature. The left side of the dotted line represents HR < 1, which is a protective factor, and the right side represents HR > 1, which is a risk factor.
