From: RNA extraction method is crucial for human papillomavirus E6/E7 oncogenes detection
Lesion progression according to E6/E7 mRNA expression in two different extraction methods. E6/E7 mRNA rates: positivity rate for E6/E7 mRNA expression (mRNA+) and negativity rate for E6/E7 mRNA expression (mRNA-). Lesion evolution was categorized into two groups: 1) Persistence: women whose cytological results had not changed in the last 2 years and, 2) Progression: women whose cytological results showed a worsened process. bioMérieux extraction method was Nuclisens manual extraction kit; Roche extraction method was High Pure Viral RNA Kit
