Multivariate logistic regression analysis to determine predictive factors associated with positive margins in patients who did not experience recurrence despite lack of additional treatment. Initial predictive variables are described in Table 4.

CI, confidence interval; CKC, cold knife conization; LEEP, loop electrosurgical excision procedure; OR, odds ratio; SE, standard error; S-T, Shimodaira-Taniguchi.
