Development and validation of a HPV-32 specific PCR assay.
Article in Virology journal, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundHuman Papillomavirus-32 (HPV-32) has traditionally been associated with focal-epithelial-hyperplasia (FEH). It is also present in 58% of oral warts of HIV-positive individuals whose prevalence is increasing. Current methods for the detection of HPV-32 are labor-intensive and insensitive so the goal of this work was to develop a highly sensitive and easy to use specific polymerase chain reaction (PCR) assay. MATERIALS AND
methodsAn HPV-32 L1 specific PCR assay was developed and optimized. The sensitivity and specificity was compared to previous assays utilized for detection (PGMY and MY09/11 PCR with dot blot hybridization) using cloned HPV-32 L1, the closely related HPV-42 L1 as well as clinical samples (oral swabs and fluids from 89 HIV-positive subjects).
resultsThe HPV-32 specific PCR assay showed improved sensitivity to 5 copies of HPV-32 as compared to the PGMY PCR, MY09/11 PCR and dot blot which had a limit of detection of approximately 3,000 copies. Using the HPV-32 dot blot hybridization assay as the gold standard, the HPV-32 specific PCR assay has a sensitivity of 95.8% and 88.9% by sample and subject, respectively, and specificity was 87.8% and 58.8% by sample and subject, respectively. The low sensitivity is due to the HPV-32 specific PCR assays ability to detect more HPV-32 positive samples and may be the new gold standard.
conclusionDue to the ease, sensitivity, and specificity the HPV-32 specific PCR assay is superior to previous assays and is ideal for detection of HPV-32 in large cohorts. This assay provides an excellent tool to study the natural history of HPV-32 infection and the development of oral warts.
