Fig. 3From: Expression and promotor hypermethylation of miR-34a in the various histological subtypes of ovarian cancerUnivariate survival analysis based on miR-34a expression. a-b PFS and OS in the entire cohort according to high and low miR-34a expression level. c-d PFS and OS in serous cancers according to high and low miR-34a expression level. Cut off used for miR-34a expression: 20th percentile of the entire cancer cohort (see results section for details). P-value calculated with log-rank testBack to article page
