Participant Flow

One woman was positive for visual inspection with acetic acid, but after enrollment was found to not have documentation of her human papillomavirus test or test result. Therefore, 320 were enrolled but only 319 participated in the study.

PRIMARY outcome

Timeframe: Immediately after treatment

Population: Not applicable; all participants were included.

Level of pain women experienced during the thermal coagulation procedure will be calculated by the number and percent of women indicating minimal to worst possible levels of pain using the Wong-Baker FACES® pain rating scale. Women's acceptability will also be assessed by asking if they would recommend the Liger Thermocoagulator treatment to a friend or relative who needed similar treatment as well as reasons for her response. Wong-Baker FACES® pain rating scale: MINIMUM value: 0 (no hurt = best outcome) Value: 2 (hurts little bit) Value: 4 (hurts little more) Value: 6 (hurts even more) Value: 8 (hurts lot more) MAXIMUM value: 10 (hurts whole lot = worst outcome)

SECONDARY outcome

Timeframe: One time, 12 months after treatment

Percentage of participants with no evidence of cervical intraepithelial neoplasia grade 2 or grade 3 (CIN2-3) at 12 months, based on histological evaluation following the standard criteria from WHO Classification of Tumours, 5th Edition, Volume 4: Female Genital Tumours.

SECONDARY outcome

Timeframe: Once, 12 months after treatment

Qualitative analysis of cervical photos by an expert colposcopist to explore factors associated with treatment failure, compared characteristics of the cervix and precancerous lesions among women with CIN2-3 at Visit 1 (enrollment) in women whose treatment resulted in lesion disappearance (\<CIN2), and women with persistent lesions (CIN2-3) at 12 months. Adequacy of the image included focus, blur, and capture; a well focused image without obstructions (blood, cysts) that captured the whole ectocervix and cervical os was considered adequate. For squamous columnar junction and transformation zone (TZ) visibility, TZ1 signifies a fully visible TZ, TZ2 signifies the TZ or visible lesions extend into the cervical canal and the TZ covers more than 75% of the ectocervix, and TZ3 signifies that the TZ is not at all visible, in accordance with WHO recommendations. Baseline histology reports histological evaluation of lesions as cervical intraepithelial neoplasia grade 2 (CIN2) or 3 (CIN3).
