Kaplan–Meier survival analysis was used for the correlation of lnc-SNHG1 and miR-216b-5p expression with the OS and DFS of patients with serous EOC. a Patients with high lnc-SNHG1 expression showed significantly shorter OS (P = 0.019, survival interval: 59.045 ± 4.373 vs 41.714 ± 4.3 months); and shorter DFS (P = 0.019, survival interval: 59.045 ± 4.373 vs 41.714 ± 4.3 months) compared with those with low lnc-SNHG1 expression. b Patients with low miR-216b-5p expression showed significantly shorter OS (P = 0.019, survival interval: 59.045 ± 4.373 vs 41.714 ± 4.3 months) and shorter DFS (P = 0.019, survival interval: 59.045 ± 4.373 vs 41.714 ± 4.3 months) compared with those with high miR-216b-5p expression
