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.
