Table 3 Proportions of individuals with potential predisposing conditions to cholangiocarcinoma development n (%)

Conditions	CCA patients (n = 39421)	Non-CCA patients (n = 18508448)	P value
Cirrhosis	1896 (4.81)	170255 (0.92)	< 0.001
Chronic viral hepatitis B infection	291 (0.74)	21797 (0.12)	< 0.001

Diabetes	4502 (11.42)	977973 (5.28)1	< 0.001

¹The number was estimated from the proportion of individuals with diabetes among 1900000 patients on whom data on diabetes were available, assuming the proportion of individuals with diabetes was similar between those with and without data on diabetes. CCA: Cholangiocarcinoma.
