Characterization of HPV Vaccination Uptake by Birth Cohorts in a Healthcare System in Pennsylvania: A Post-COVID-19 Pandemic Historical Cohort Assessment.
Article in Cancer control : journal of the Moffitt Cancer Center. 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
BackgroundCOVID-19 pandemic-related disruptions in primary care caused delays in in-person well visits for patients that were age-eligible to receive recommended preventive healthcare services. Vaccine schedules impacted by disruptions led to delays in administration of human papillomavirus (HPV), tetanus, diphtheria, and acellular pertussis (Tdap), and quadrivalent meningococcal (MenACWY) vaccines, but some studies report inconsistent findings. Our study sought to characterize changes in HPV vaccination patterns during the COVID-19 pandemic by birth cohorts in South Central Pennsylvania, compared to changes in Tdap and MenACWY vaccination.MethodsOur methodological approach consisted of survival analysis techniques, such as Kaplan-Meier survival curves and Cox proportional hazards models. Patient data were analyzed by separate birth cohorts and groups of birth cohorts, with a primary interest on younger birth cohorts during the COVID-19 pandemic.ResultsDemographic and vaccination data from 29 928 patients born between January 1, 2000 and December 31, 2014 were analyzed. Overall, 80.1% had been vaccinated against Tdap, 81.8% against meningitis, and 67.1% against HPV by the age of 17. The adjusted hazard ratio (aHR) for HPV vaccine initiation by age 12 was the highest for patients born between 2009 and 2010 (aHR = 2.52; 95% CI: 2.34, 2.70), when compared to patients born between 2000 and 2002. However, this observation was also accompanied by a slowed increase in uptake from 63.5% (birth cohort 2006-2008) to 65.2% (birth cohort 2009-2010). ConclusionUnderstanding changes in vaccination uptake by birth cohorts informs the efforts of researchers and primary care practitioners to identify best practices tailored to the vaccination gaps for each group.
