a In serous carcinoma, the relative level of miR-34a showed no significant difference between the early-stage OC group and the advanced-stage OC group. b In non-serous carcinoma, the relative level of miR-34a in the early-stage OC group was significantly higher than that in the advanced-stage OC group. c In clear cell carcinoma, the relative level of miR-34a in the early-stage OC group was significantly higher than that in the advanced-stage OC group
