Comparative Effectiveness of Cell-Based Versus Egg-Based Influenza Vaccines in Prevention of Influenza Hospitalization During the 2022-2023 Season Among Adults 18-64 Years.
Article in Influenza and other respiratory viruses, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
This retrospective cohort study evaluated the comparative vaccine effectiveness (cVE) of licensed standard-dose cell-based versus egg-based influenza vaccines in preventing influenza hospitalization among adults 18-64 years during the 2022-2023 season. The cohort included eligible Kaiser Permanente Southern California members who received ≥ 1 dose of influenza vaccine (n = 848,334). The adjusted cVE against influenza hospitalization was -10.1% (95% CI: -49.8%, 37.8%) in the 18- to 49-year-old cohort. In the 50- to 64-year-old cohort, the adjusted cVE was 14.9% (-33.8%, 52.1%). Cell-based and egg-based influenza vaccines conferred comparable protection against influenza hospitalization in adults 18-64 years of age in the 2022-2023 season.
