Associations of KLK mRNA expression with clinical parameters in advanced high-grade serous ovarian cancer

Clinical parameters	KLK7a low/high	KLK5 + KLK7b low/high
Age	p = 0.564	p = 0.141
≤ 60 years	40/18	26/32
> 60 years	56/25	46/34
Residual tumor mass	p = 0.234	p = 0.041
0 mm	51/19	43/27
> 0 mm	44/23	29/37
Ascites fluid volume	p = 0.261	p = 0.244
≤ 500 ml	54/24	45/32
> 500 ml	41/13	26/28

^a Chi-square test (cut-off point: KLK7 = 67th percentile)

^b Chi-square test (dichotomized into low level by KLK5 low and KLK7 low, and high level by KLK5 high and/or KLK7 high; cut-off point: KLK5 = 67th percentile, KLK7 = 67th percentile)

Due to missing values, numbers do not always add up to n = 139.
