The association between post-treatment surveillance testing and survival in stage II and III colon cancer patients: An observational comparative effectiveness study

Table 4 IPTW-adjusted hazard ratios for the association between surveillance status and 5-year cancer-specific, noncancer-specific, and overall mortality

	5-year Cancer-specific death (events = 3459)^a		5-year Noncancer-specific death (events = 1256)^{a, b}		5-year Overall mortality (events = 5723)^a
Surveillance Status	HR (95% CI)	P Value	HR (95% CI)	P Value	HR (95% CI)	P Value
