Using immunization registry data to explore initiation of HPV vaccination at ages 9 and 10.
Article in Human vaccines & immunotherapeutics, 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
Despite evidence highlighting benefits of age 9/10 initiation of human papillomavirus (HPV) vaccination, little is known about who is initiating the series earlier. We describe the population of children who initiate earlier and assess the relationship of earlier initiation with series completion. We used individual-level immunization registry data from Iowa which contained data on male (49.9%) and female (50.1%) children born between 2004-2013 ages 9 and 17. We compared sociodemographic characteristics using chi-square statistics and used logistic regression to assess odds of initiation. Of children with a record of HPV vaccination, only 3.2% initiated early. In comparison to children who initiated at later, the early initiator group had a higher percentage of females (
