Incidence, Mortality, and Predictive Factors of Hepatocellular Carcinoma in Primary Biliary Cirrhosis

Table 3

Standardized incidence ratio (SIR) and standardized mortality ratio (SMR) of HCC in primary biliary cirrhosis.

	Number of incidence of HCC
	Observed	Expected	SIR	95% Cl
Overall	13 (12)	1.1 (1.0)	11.6 (11.5)	6.2–19.8 (6.0–20.2)
Female	11 (10)	0.5 (0.5)	20.4 (19.8)	10.2–36.5 (9.5–36.4)
	Deaths due to HCC
	Observed	Expected	SMR	95% Cl
Overall	9	0.9	11.2	5.4–20.6
Female	8	0.4	21.5	9.8–40.7

Including all years of follow up (Excluding experience in first year after diagnosis of primary biliary cirrhosis); CI: confidence interval; HCC: hepatocellular carcinoma; SIR: standardized incidence ratio; SMR: standardized mortality ratio.
