Ki-67 Expression in CRC Lymph Node Metastasis Does Not Predict Survival

Table 5

Survival analysis: frequency and relative frequency for overall survival and medium of time to death.

Ki-67	Tissue		Deaths; (%)	Median for survival time; 95% confidence interval	Log-rank test
Negative	CRC	154	53 (65.6)	65.00 [59.49–70.52]	0.321
Positive		332	125 (62.3)	62.09 [58.06–66.12]
Negative	Lymph node	49	17 (65.3)	63.48 [53.18–73.79]	0.131
Positive		62	30 (51.6)	50.07 [41.06–59.08]
