Distribution of human papilloma virus genotypes in cancerous lesions of cervix: Insights from a hospital-based study in Bangladesh.
Article in Journal of education and health promotion, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundPersistent infection with high-risk human papillomavirus is a primary contributor to the development of cervical precancerous lesions and cervical malignancy. Understanding the hrHPV genotype prevalence is essential for guiding vaccination and screening strategies. This study was done to determine the prevalence of high-risk HPV genotypes in women with histopathologically confirmed cervical cancer and precancerous cervical lesions. MATERIALS AND
methodsThis was a descriptive cross-sectional study conducted at the Colposcopy Clinic in the Department of Gynecologic Oncology, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh, between August 2022 and July 2024. A total of 300 women aged 25 years or older with histologically confirmed cervical lesions (125 with CIN and 175 with invasive cervical cancer) were enrolled.
resultsAmong 175 invasive cervical cancer cases, 152 (86.9%) were hrHPV-positive. HPV-16 was the most common genotype, detected in 104 (68.4%) of hrHPV-positive cases as a single infection and 116 (76.3%) as a dominant type in multiple infections. Other notable genotypes included HPV-18 (4.6%), HPV-39 (3.3%), and HPV-35, 52, and 59 (each 2.6%). HPV types 45, 66, and 68 were among the less commonly identified high-risk genotypes, each accounting for 3 (2.0%) of cases. Multiple hrHPV infections were observed in 17.1% of cancer cases. Histologically, squamous cell carcinoma was the predominant subtype in both HPV-positive and HPV-negative groups.
conclusionThe predominance of HPV-16 underscores the need to expand national HPV vaccination and screening programs, using genotype-specific data to guide policies aligned with the WHO's cervical cancer elimination strategy.
