The impact of HR HPV prevalence on the efficiency of HPV test\u2010based screening has never been directly evaluated. A meta\u2010regression of the relationship between HR HPV prevalence and the specificity and positive predictive value (PPV) of HPV DNA testing for the presence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) was performed. Only studies that used Hybrid Capture 2 (HC2) were included. Country income (low\u2013medium <jats:italic>vs<\/jats:italic>. high) was used as a proxy of previous screening. Twenty\u2010six populations from 20 studies were included. For a 10% increase in HR HPV prevalence, HC2 specificity decreased by 8.41% [95% confidence interval (CI): 8.02\u20138.81], whereas PPV increased by 4.74% (95% CI: 2.45\u20137.03). HR HPV prevalence explained 98% of the variability in HC2 specificity and 38% of the variability in PPV. Country income did not affect specificity, but low\u2013medium income was associated with higher PPV (3.81%; 95% CI: 1.53\u20136.10) after adjustment for HR HPV prevalence. When HR HPV prevalence is high, the specificity of HPV testing for CIN2+ decreases, but PPV does not decrease and it is high in inadequately screened populations. The number of HPV\u2010positive women needing further assessment or treatment per CIN2+ case detected will therefore decrease and screening efficiency will improve. This is explained by the fact that HR HPV causes CIN2+: an increase in HR HPV prevalence is inevitably accompanied by an increase in CIN2+.<\/jats:p>","DOI":"10.1002\/ijc.26147","type":"journal-article","created":{"date-parts":[[2011,4,25]],"date-time":"2011-04-25T13:25:54Z","timestamp":1303737954000},"page":"1387-1394","source":"Crossref","is-referenced-by-count":53,"title":["HPV prevalence and accuracy of HPV testing to detect high\u2010grade cervical intraepithelial neoplasia"],"prefix":"10.1002","volume":"130","author":[{"given":"Paolo","family":"Giorgi\u2010Rossi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvia","family":"Franceschi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guglielmo","family":"Ronco","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2011,8,2]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1002\/1097-0258(20000715)19:13<1783::AID-SIM497>3.0.CO;2-B"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.vaccine.2008.06.019"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1097\/QAD.0b013e32833f39b2"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0020-7292(00)00329-5"},{"key":"e_1_2_7_6_2","unstructured":"The World Bank Group.
