Multivariate Cox Proportional Regression Analysis for the Association of Total FAK Staining Scores With Recurrence/Progression-Free Survival (n = 52)

Variable	FAK Staining Scores Treated as Continuous Variables
	P	HR (95% CI)
FAK staining score	.196	0.998 (0.995–1.001)
SCLC disease stage (limited vs extensive)	.0002	0.219 (0.099–0.485)
Age	.032	1.053 (1.004–1.105)
Sex	.823	1.086 (0.526–2.241)
Smoking status (non-current vs current)	.045	0.412 (0.173–0.980)

CI, confidence interval; FAK, focal adhesion kinase; HR, hazard ratio; SCLC, small-cell lung carcinoma.
