Socioeconomic disparities in influenza vaccination uptake: impact of the COVID-19 pandemic in South Korea.
Article in BMC public health, 2025. 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
backgroundThis study aimed to investigate the sociodemographic and behavioral factors related to increased influenza vaccination uptake during the COVID-19 pandemic in South Korea, particularly among adults not eligible for free vaccination.
methodsAnalyzing data from 78,815 participants in the Korea National Health and Nutrition Examination Survey (2010-2021), we assessed trends in influenza vaccination coverage. Various sociodemographic factors, behavioral aspects, and psychological stress levels were assessed using multivariable logistic regression to evaluate the difference in vaccination response during pre-/post-COVID-19 periods.
resultsLowest income quartile households exhibited decreased influenza vaccination uptake during the pandemic (adjusted odds ratio 0.67, p = 0.011), whereas higher income quartiles exhibited increased uptake. In the lowest income households, unemployed status of household was additionally associated with decreased influenza vaccine uptake (adjusted odds ratio 0.50, p = 0.003).
conclusionsThis study identified income-based disparities in the responsive increase of influenza vaccination during the COVID-19 pandemic. Lower-income households exhibited a disproportionate reduction in influenza vaccine uptake, emphasizing the need for targeted support systems and expanded free vaccination for prioritized groups to address these disparities.
