From: Diagnostic imaging of cervical intraepithelial neoplasia based on hematoxylin and eosin fluorescence
Linear regression analysis of segmental fluorescence intensity. a Cervical epithelium divided into equidistant segments: segment 1 (bottom third), segment 2 (middle), and segment 3 (upper third). b Fluorescence intensity profile of the line plotted in (a). Bisecting lines represent the 89th percentile of each segment. c The highest fluorescence intensity values (top 10 %) of each segment from (b) are averaged, plotted in (c) and analyzed with linear regression. Total samples in each histological category are Normal = 13, CIN I = 18, CIN III = 12
