Statistical analysis
OVARIAN CANCER, STAGE I, RECURRENCE
Most of the biomarkers analyzed were prespecified (CA‐125, CRP, insulin, IGF‐1, and leptin). Analyses of adiponectin, IL‐6, TNF‐α, and VEGF were unplanned and thus are considered exploratory.A mixed model repeated measures analysisSurvival analysis is exploratory as an unplanned outcome. Kaplan Meier analysis was performed to compare the overall survival experience between groups. The Cox proportional hazards model was used to evaluate the effect of baseline characteristics, including age at enrollment, BMI, time since diagnosis, family history of ovarian cancer, stage, recurrence prior to enrollment, and employment. Multivariate analysis was performed to control for these potential confounding effects. The supremum test was used to check proportional hazards assumption. A two‐sided 0.05 significance level was applied for all analyses. All analyses were conducted using SAS, Version 9.4 (SAS).
