Table 2B. Multivariate modelling for PFS in KRas WT patients.

	HR (95% CI)	P-value
Age: median	0.68 (0.23–2.0)	0.49
Gender	1.35 (0.47–3.83)	0.57
Race	1.20 (0.44–3.27)	0.72
White vs minorities (Black, Hispanic, Other)
Telomere length	0.31 (0.10–0.98)	0.048

Abbreviations: CI=confidence interval; HR=hazard ratio; PFS=progression-free survival; WT=wild type.

Results of multivariate modelling that included all univariate variables with P<0.20, and with forcing of age, gender, and race. The TL was significant for PFS in this multivariate model with a HR of 0.32 with P=0.048.
