Acceptable predictive accuracy of histopathology results by colposcopy done by Gynecology residents using Reid index

The aim of this study was to determine the strength of the correlation between colposcopic impression according to Reid colposcopic index (RCI) done by Gynecology residents and biopsy histology in a university hospital. Colposcopy was performed on 260 women. According to RCI, the scores zero, one, or two were given to each of four standardized colposcopy patterns (acid staining, iodide staining, margin of lesion, and vascular pattern) and the total score was calculated. In those with multiple lesions, the patterns with the highest score were considered. Then the biopsy was obtained from the lesion and put in formalin for pathological evaluation. There was a statistically significant association between colposcopy findings and histopathology findings and the score was increased as parallel as malignancy grade (r = 0.680, P
