2.4. Data Abstraction
The data were prepared in a standardized manner. We recorded the
demographics and study information of patients, including author,
evidence level(EL), population age range, gender, and study type. In
addition, lesions, laser setting, clinical outcomes, results, and
findings are based on the reference standard. Complications, recurrence,
remission, clearance, cure rate, and relative data (when given) were
also abstracted. The primary outcome was the cure rate. Secondary
outcomes were the recurrent rate, death rate, remission rate, clearance
rate, effective rate, and HPV-detected rate. The postoperative
complication rate was the safety outcome measure.
