Distribution of results for wide-spectrum, low-risk, and high-risk HPV in different grades of CIN. There was no significant difference of wide-spectrum HPV DNA between CIN 1 (87%), and CIN 2 (91%), CIN 3 (96%) (P=0.941). The difference in the distribution of high-risk HPV between CIN 1 and CIN 2 and 3 together (CIN 2/3) was highly significant (P<0.001).
