Prophylactic immunization with human papillomavirus vaccines induces oral immunity in mice.
Article in The Laryngoscope, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
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
objectiveAlthough it has been shown that prophylactic vaccination can induce genital immunity, there is inadequate information on human papillomavirus (HPV) vaccine-induced oral immunity, which is of particular interest due to HPV-associated oropharyngeal malignancies and recurrent respiratory papillomatosis. Therefore, we assessed the efficacy of various HPV vaccines against oral HPV pseudovirus (PsV) infection in mice. STUDY
designPreclinical scientific investigation.
methodsC57BL/6 mice were vaccinated three times at 2-week intervals with either Gardasil (Merck, Kenilworth, NJ) (50 µL intramuscular injection) or a candidate pan-HPV L2 vaccine with alum adjuvant (25 µg subcutaneous injection). Additional mice were immunized with passive transfer of either Gardasil (Merck) human antisera or nonimmunized sera (100 µL intraperitoneal injection). All vaccinated and naïve control mice were then challenged with HPV16 E6E7 luciferase PsV in the oral mucosa. Visualization of HPV PsV infection was monitored through in vivo luciferase imaging.
resultsOral luciferase-expressing HPV16 PsV infection was not detected in Gardasil (Merck), L2 vaccine, and Gardasil (Merck) antisera-immunized mice, whereas robust luciferase expression was observed in all control mice. An in vitro neutralization assay from sera of Gardasil-vaccinated (Merck) mice confirmed that vaccine efficacy was due to neutralizing antibodies.
conclusionOral HPV16 PsV infection in mice was completely prevented with all methods of prophylactic HPV immunization. These findings provide preliminary evidence that human vaccines induce protection against oral HPV infection, which has significant public health implications for HPV-associated oropharyngeal malignancies.
