Testing for NRAS Mutations in Serous Borderline Ovarian Tumors and Low-Grade Serous Ovarian Carcinomas

Table 3

Results of survival analysis with NRAS mutation status as a predictor.

Idylla NRAS	Log-rank test	Wilcoxon-Breslow-Gehan test	Tarone-Ware test
χ^2 statistic	7.2735	6.8182	7.0455
Degrees of freedom	1	1	1
-value	0.0070	0.0090	0.0079

Irrespective of the type of statistical test, the presence of NRAS mutation was identified as a significant predictor of worse survival ().
