Our study population included only women with the diagnosis of high-grade intraepithelial lesion (HSIL) in the pathologic examination of the TZE surgical specimen. Positive margins were defined as the presence of HSIL in the endocervical and\/or ectocervical margin of the specimen. Factors evaluated included demographic characteristics, pretreatment Pap smear and human papillomavirus test, colposcopic findings, TZE indication, and pathologic features of the surgical specimen. We performed univariate analysis and logistic regression modeling including variables associated with the outcome of positive margins in the univariate analysis.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Our sample included 264 women, with a 15.2% positive margins rate (40 patients). In the univariate analysis, patients with immunocompromised status, HSIL Pap smear, and higher number of quadrants involved in colposcopic examination were more likely to have positive margins. After multivariate analysis, only immunocompromised status was found to be an independent risk factor (odds ratio = 4.94; 95% CI = 1.43\u201317.15; <jats:italic toggle=\"yes\">p<\/jats:italic> &lt; .05).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Immunocompromised status was the sole significant predictor for positive margins in TZE surgical specimens.
