Univariate logistic regression analysis of variables affecting HCV screening
| Variable | Adjusted OR (95% CI) |
| Race | |
| African-American | 1.0 |
| White | 0.76 (0.61 to 0.95) |
| Other | 1.14 (0.75 to 1.73) |
| Sex | |
| Female | 1.0 |
| Male | 1.09 (0.88 to 1.35) |
| Socioeconomic quartile | |
| First | 1.0 |
| Per lower quartile | 0.90 (0.81 to 0.99) |
ORs for HCV screening were determined for race, gender and socioeconomic quartile using the open-source statistical program R. Low socioeconomic standing and white race were associated with a lower likelihood of screening (significant variables in bold).
