Relative frequencies of high-risk HPV pairings in women with abnormal cytology. Includes results from 166 women with abnormal cervical cytology. Circle size reflects relative frequency of occurrence such that smaller circles reflect less frequent observations. The most frequently observed pairings are labeled (HPV 31 and HPV 58, n = 10 occurrences; HPV 56 and HPV 58, n = 9 occurrences; HPV 56 and HPV 16, n = 8 occurrences). Pair = None refers to HPV type frequency alone, without another high risk HPV type
