Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Current primary outcome measures as of 12/03/2018: 1. CIN grade 3 or greater (CIN3+) detected over the four years post recruitment in the control and intervention arms evaluated and compared as a surrogate marker for estimating reductions in incidence of cervical cancer, measured at four years Previous primary outcome measures: 1. Histologically confirmed cervical intraepithelial neoplasia (CIN) greater than or equal to grade two detected at two years in both the control and safety-check arms 2. CIN grade three (CIN3) or greater detected over the four years post recruitment in the control and intervention arms evaluated and compared as a surrogate marker for estimating reductions in incidence of cervical cancer, measured at four years 3. Detection of histologically confirmed greater than or equal to CIN3 in the participants allocated to six month re-testing, measured at two years 4. Total estimated cost per woman screened and total estimated cost per quality-adjusted life-year gained for each technology, measured at four years | — |
Secondary
| Measure | Time frame |
|---|---|
| Current secondary outcome measures: 1. Histologically confirmed cervical intraepithelial neoplasia grade 2 or greater (CIN2+) two detected at two years in both the control and safety-check arms 2. CIN2+ detected in the control and intervention arms over the four years post recruitment 3. Clearance of HPV infection in women who are HPV positive at recruitment, measured at two and four years 4. Detection of histologically confirmed greater than or equal to CIN3 in the participants allocated to 12 month re-testing, measured at two years 5. Evaluation of the impact of primary HPV testing on colposcopy services through evaluation of colposcopy referral rates in each arm through the trial follow-up period 6. Total estimated cost per woman screened and total estimated cost per quality-adjusted life-year gained for each technology, measured at four years Previous secondary outcome measures: Clearance of HPV infection in women who are HPV positive at recruitment, measured at two and four years | — |
