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 the leading cause of sexually transmitted infections (STIs). It is found in extragenital regions, including the oropharyngeal cavity. Its presence in this area is linked to the increased prevalence of oral and pharyngeal cancer cases in young individuals, which is associated with current sexual practices in the young population. Objective, the objective of this study was to estimate the prevalence of HPV infection in the oropharyngeal cavity and identify associated factors within the student community of the Engineering and Chemical Sciences Unit of the University of Veracruz.
methodsan observational, descriptive, and transversal study was conducted. The study included 136 sexually active students aged 18 to 25 without oropharyngeal infection. After obtaining informed consent from all participants, mouthwashes were collected from the oropharyngeal cavity for subsequent detection of viral DNA and HPV genotyping using the PCR-RFLP technique. Risk factors were further assessed through a private questionnaire. For statistical analysis, a bivariate analysis of the main risk factors was performed, and Odds Ratios (OR) and 95% Confidence Intervals (CI) were calculated.
resultsThe results showed that HPV was detected in 6 participants, resulting in a prevalence of 4.4% (95% CI, 0.92-7.91), with genotypes 11, 52 and 58 identified. Notably, participants with a sexual orientation other than heterosexual had a 7.5-fold higher association with HPV.
conclusionsthese findings indicate that low- and high-risk HPV infection in the oropharyngeal cavity is associated with risky sexual behavior in young individuals. Therefore, understanding the specifics of sexual activities is necessary to better comprehend viral transmission and spread among HPV-positive students.
