Table 3.

Multivariable analysis of breast cancer-specific 5-year overall survival, breast cancer metastasis, and breast cancer-specific recurrence by Claudin expression status. Model 1 is crude; Model 2 is adjusted by age at the time of diagnosis and treatment course; Model 3 is adjusted by age and other covariates, as described in Table 1. The hazard ratio is calculated using the log-rank test, and statistical significance is defined as p < 0.05.

		Model 1	Model 2	Model 3
Breast cancer-specific 5-year overall survival	HR (%95 CI)	0.48 (0.13, 1.27)	0.54 (0.20, 1.43)	0.58 (0.18, 1.82)
	P-value	0.123	0.806	0.338
Breast cancer metastasis	HR (%95 CI)	0.64 (0.23, 1.27)	0.60 (0.21, 1.67)	0.52 (0.15, 1.52)
	P-value	0.203	0.331	0.409
Breast cancer-specific recurrence	HR (%95 CI)	0.86 (0.83, 8.96)	0.84 (0.78, 9.32)	0.83 (0.70, 10.2)
	P-value	0.967	0.856	0.675
