Genotyping and Phylogenetic Analysis of Human Papillomaviruses in Formalin Fixed Paraffin Embedded Sections from Cervical Lesions in Duhok-Iraq.

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
objectiveHuman papillomavirus (HPV) has been identified as an important causative factor in cervical cancer development. Cervical cancer is the fourth most prevalent malignant tumor among women globally. The purpose of this study was to investigate the prevalence and genotyping sequences of HPV in formalin-fixed paraffin-embedded (FFPE) cervical tissue using conventional polymerase chain reaction (PCR), and HPV-DNA sequencing. MATERIAL AND
methodsRetrospective cross-sectional study. Forty (FFPE) blocks with different cervical lesions were taken; patients' ages ranged from 24 to 65 years. Detection and sequencing of HPV DNA were done by conventional PCR (L1 gene), which was achieved by universal PCR primers (MY09/11 oligonucleotides). Then sequencing and phylogenetic tree was constructed.
resultsNine samples were found positive and detected by conventional PCR, they were identified in CIN1 and SCC at 7.5% (n=3) for each, 5.0% (n=2) KA, and 2.5% (n=1) in CIN3 cases, after sequencing were submitted to GenBank and accession numbers were obtained. The phylogenetic tree was constructed and the aligned sequences showed high homology with the nucleotide sequence of the references from the Genbank database. HPV 11, 16, 18, 22, 33, 52, and 58 were found to have little nucleotide heterogeneity and thus no amino acid heterogeneity. Conclusion: Sequencing and phylogenetic analysis of circulating HPV types in Duhok provides very essential data about nucleotides and amino acid heterogeneity, to reveal genetic diversity with strains included in the vaccines that have not been introduced to Iraq yet.
