Genotypic distribution and molecular epidemiology of HPV in women in the UAE using PNA-based RT PCR.

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
objectivesThis study aimed to determine the genotypic distribution and molecular epidemiology of HPVs in PAP smear samples of women in the UAE using a peptide nucleic acid (PNA)-based fluorescence melting curve analysis method.
methodsA cross-sectional retrospective study was conducted between January 2024 to January 2025 after receiving ethical approval from the Institutional Review Board of Gulf Medical University. A total of 229 liquid-based cervical cytology samples were obtained from women aged 20-55 years attending the Gynaecology out-patient department of Thumbay University Hospital and other hospitals of the UAE, processed for the routine cytological examination to identify and differentiate morphological changes of the PAP smears. HPV genotyping was performed using PNA-based fluorescence melting curve analysis by the RT-PCR method.
resultsA total of 191 HPV genotypes were detected in 96 HPV positive PAP smear samples, including 47 abnormal cytology and 49 NILM samples. 137 HR and 54 LR-HPV genotypes were identified in all 96 positive samples. The highest rate of mixed HR and LR-HPV genotypes (18%) was detected in women aged 31-40 years old. HR53, 16, 68, 66, 31, 35, and LR6 were the predominant genotypes. Mixed HR and LR-HPV infection is present in 26% cases; in that HPV53 was the primary genotype, followed by HPV35, 66, 11, 43, 81, 61, and 6.
conclusionThe genotypes 53, 16, 68, 66, 31, 61, 35, and 6 were the most common genotypes detected in the PAP smear samples. Notably, 21% of normal epithelial cells of the PAP smear samples tested positive for different HR-HPV genotypes. These findings underscore the crucial role of HPV genotyping using RT-PCR, enhancing the effectiveness of screening surveillance and providing foundational data for future prospective studies, vaccination impact assessments, and targeted screening strategies.
