Downregulation of miR503HG predicted poor survival of OC patients. qPCR was performed to measure the expression levels of miR503HG in both OC and non-tumor biopsies from the 61 OC patients included in this study. Differences in expression levels between OC and non-tumor biopsies were explored using paired t test (a). To perform survival analysis, the 61 OC patients were divided into the high (n = 31) and low (n = 30) miR503HG level groups. Survival curves were plotted using K-M plotter and compared by log-rank test (b). PCR reactions were repeated 3 times and mean values were presented, p < 0.05
