^±Totals of each category of discrete variables may not equal 318 due to missing data. For continuous variables, there is no missing data for age or platelet level. For BMI, N=8 missing data, and for CA-125 N=88 for missing data.

^†Discrete variables were analyzed with Fisher’s exact contingency tables, continuous variables were analyzed with sample t-test
