Associations between concentrations of human papillomavirus (HPV) 16 DNA and risk for cervical cancer
| Quintiles of mean HPV 16 threshold cycle number(Ct)* | Adjusted odds ratio (95% CI)† |
|---|---|
| *Lower values of Ct denote higher concentrations of HPV 16 DNA. | |
| †Odds ratio adjusted for level of β actin. | |
| HPV 16 negative | 1.0 |
| HPV 16 positive, Ct value 44.8 to 50.0 | 2.0 (1.1 to 3.8) |
| HPV 16 positive, Ct value 41.25 to 44.8 | 4.4 (2.3 to 8.3) |
| HPV 16 positive, Ct value 38.99 to 41.25 | 8.1 (3.8 to 17.3) |
| HPV 16 positive, Ct value 36.66 to 38.99 | 18.7 (7.1 to 49.5) |
| HPV 16 positive, Ct value <36.66 | 68.8 (15.8 to 299.6) |
