Multinomial logistic regression analysis on surgery and lymph node biopsy.

Characteristics	1 = no surgery, no biopsy (n = 254, 5%)			2 = oophorectomy ± hysterectomy, had biopsy (n = 838, 15%)			3 = oophorectomy ± hysterectomy, no biopsy (n = 1197, 22%)			5 = oophorectomy with omentectomy (or debulking), no biopsy (n = 1129, 21%)
