The correlation of grade 3/CCC with age, endometriosis, and FSS

Variables	Grade1-2 (N = 84)	Grade 3/CCC (N = 24)	p value
Age			< 0.001
≤ 30	52(61.9%)(94.5%)	3(12.5%)(5.5%)
> 30	32(38.1%)(60.4%)	21(87.5%)(39.6%)
Endometriosis			0.002
No	73(86.9%)(83.9%)	14(58.3%)(16.1%)
Yes	11(13.1%)(52.4%)	10(41.7%)(47.6%)
Type of surgery			< 0.001
RS	35(41.7%)(62.5%)	21(87.5%)(37.5%)
FSS	49(58.3%)(94.2%)	3(12.5%)(5.8%)

We calculated both the row and column percents. The first percent in the cell was the column percent representing a proportion in the “grade” arm, and the second was the row percent representing a proportion in the “age,” “endometriosis,” and “FSS or RS” arm

CCC clear-cell carcinoma, RS radical surgery, FSS fertility-sparing surgery
