TeenVac.org: A Mobile Web App to Improve Human Papillomavirus Vaccine Uptake for Adolescent Boys.

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
purposeHuman papillomavirus (HPV) vaccine uptake remains below the Healthy People 2030 goal of 80% series completion in the United States. Parental concerns about the efficacy and safety of the vaccine remain and may be addressed by digital interventions tailored to their concerns.
methodsA randomized trial was conducted between May 2019 and December 2020, testing a mobile web app (TeenVac.org) for parents and adolescent sons (11-14 years, N = 209) that encouraged HPV vaccination. Parents and adolescent sons were randomized to receive either the TeenVac app or the Centers for Disease Control and Prevention (CDC) HPV vaccination pamphlet online. Participants had access to the TeenVac or CDC pamphlet for the 9-month study duration. Adolescent sons' vaccination records were collected from the state vaccine registry at the end of the study.
resultsIntent-to-treat and web usage analyses were conducted. Intent-to-treat analyses found that adolescent sons of parents randomized to the TeenVac app were significantly more likely to complete the HPV vaccination series than those randomized to the CDC pamphlet group (Pearson χ DISCUSSION: The TeenVac app meaningfully impacted HPV vaccine series completion, particularly among parents who used the web app. The results provide further evidence that digital interventions can improve vaccine uptake when focused on parents' and sons' vaccine-related concerns.
