Prevalence and age-related trends of high-risk Human Papillomavirus genomes in Ecuadorian women: a comprehensive cross-sectional study.
Article in BMC infectious diseases, 2025. 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
backgroundHuman Papillomavirus (HPV) is a leading cause of cervical cancer worldwide. Previous studies on HPV prevalence in Ecuador have presented inconsistent findings due to limited sample sizes and regional foci. This study aims to estimate the prevalence and characteristics of HPV infection in Ecuadorian women, identifying high-risk HPV genomes and age-related trends, using data from the Cervical Cancer Screening and Prevention Program.
methodsData were collected from multiple health centers across Ecuador, particularly focusing on the province of Pichincha, utilizing GeneXpert technology and the Xpert
resultsOf 16,197 valid tests, 1,776 were HPV-positive, yielding a prevalence of 11.0%. Women aged 30-39 were the most affected demographic, accounting for 39.7% of positive cases. The most common HPV genomes identified were 31/33/35/52/58, constituting 42.3% of HPV-positive women (P3 pooled). The prevalence of multiple HPV genome infections was 13.8%.
conclusionsThe study provides a more nuanced understanding of HPV prevalence in Ecuador, indicating that HPV rates are lower than previous national studies but higher than global estimates. The results lay essential groundwork for targeted public health interventions and suggest the need for future research to address methodological limitations.
