Impact of HCV infection and ethnicity on diabetes risk between 1990–2015 in British Columbia Hepatitis Testers Cohort, using multivariable Fine-Gray subdistribution proportional hazards models*

Covariate	aHR (95% CI), PS-matched dataset	aHR (95% CI), PS-weighted dataset
HCV-negative Other	1 (ref)	1 (ref)
HCV-negative East Asian	1.10 (0.93 to 1.30)	1.21 (1.02 to 1.42)
HCV-negative South Asian	2.34 (1.98 to 2.77)	2.42 (2.05 to 2.87)
HCV-positive Other	2.27 (2.14 to 2.41)	3.18 (2.70 to 3.73)
HCV-positive East Asian	3.24 (2.76 to 3.81)	2.27 (2.14 to 2.40)
HCV-positive South Asian	5.76 (4.98 to 6.67)	5.71 (4.93 to 6.60)

*Multivariable models were adjusted with sex, age at HCV diagnosis, material and social deprivation quintiles, HBV/HIV infection, obesity, mood and anxiety disorders, alcohol use disorder and injection drug use.

aHR, adjusted hazard ratios; CI, confidence interval; HCV, hepatitis C virus; PS, propensity scores.
