1Genomic instability was quantified as below (TAI<med.) or above (TAI>med.) median TAI. The median was 0.135 for the Norwegian cohort and 0.242 for the Australian cohort.
Calculated p-values for age, stage, and grade from Mann-Whitney tests and for chemotherapy and progression from Fisher's exact tests.
Abbreviations: SOC, serous ovarian cancers; TAI, Total Aberration Index; PFS, progression-free survival; OS, overall survival; CI, confidence interval.
