COVID-19 vaccination preferences during a pause in Johnson & Johnson vaccine administration.
Article in Vaccine: X, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
In April 2021, the US paused Janssen (J&J) COVID-19 vaccination because of reported blood clots post vaccination. This paper explores how vaccine decision-making--receiving a J&J vaccine right away vs waiting for a Pfizer vaccine--changed during the pause. In an opt-in internet-based survey April 2021 with 915 participants, 37 % were not vaccinated. Of these, 18 % would accept a J&J vaccine, 5 % would wait 1 month for a Pfizer vaccine, 25 % would wait 3 months, and 52 % would not want any vaccine. Among the unvaccinated, 56 % had heard of blood clots; 61 % of these did not want any vaccine, compared to 41 % of those who had not heard of blood clots. Moreover, among those vaccine hesitant in general, 11 % would still obtain a J&J vaccine if offered right away. These findings may suggest spillover of brand-specific adverse event concerns to the vaccine product as a whole.
