Human papillomavirus types in non-cervical high-grade intraepithelial neoplasias and invasive carcinomas from San Luis Potosí, Mexico: a retrospective cross-sectional study.
Article in Infectious agents and cancer, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundViral infections and the burden of high-grade intraepithelial neoplasias (HIN) and invasive carcinomas (IC) associated to infections by human papillomavirus (HPV) types may be prevented by type-specific anti-HPV vaccines. This study determined the prevalence of HPV types in non-cervical HIN and IC diagnosed from 1999 to 2011 at a general hospital in San Luis Potosí, Mexico.
methodsReview of the 67 formaldehyde-fixed paraffin-embedded non-cervical specimens initially diagnosed as HIN (n = 28) or IC (n = 39) confirmed the presence of tumor tissue in 63 of them and changed the diagnosis of 24 from HIN to low-grade intraepithelial neoplasias, that were excluded from the study. HPV DNA was detected with the SPF10-DNA enzyme immunoassay in the 39 cases included, and viral types in the HPV-positive tumors were identified with the INNO-LiPA linear probe array.
resultsAmong the cases included, four HIN were located in the vagina (n = 3) and vulva (n = 1), and 35 IC in the oral cavity (n = 19), penis (n = 8), vagina (n = 7) and vulva (n = 1). There were 13 HPV-positive cases from the vagina (n = 7), vulva (n = 1), penis (n = 1) and oral cavity (n = 1). The viral types identified were the high-risk types HPV16 in the vagina (n = 3) and vulva (n = 3), HPV45 in the vagina (n = 2), HPV59 in the vagina (n = 1) and penis (n = 1), HPV33 in the vagina (n = 1),and HPV35 in the tongue(n = 1); and the low-risk types HPV54 in the vagina (n = 1), and HPV11 in the vulva (n = 1).
conclusionsFive high-risk viral types (HPV16, 45, 59, 33 and 35) and two low-risk types (HPV11 and 54) infect one third of the non-cervical HIN and IC included. Most infections are by a single HPV high-risk type, the most prevalent one being HPV16. Vagina is the most frequent location of the HPV-positive tumors. Vaccination against HPV16 and HPV18 could have prevented around half of the HPV-positive tumors.
