Influencing Factors of Pregnant Women's Willingness to Receive Influenza Vaccination in China.
Article in Vaccines, 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
backgroundSeasonal influenza presents a major public health issue with a heavy disease burden on pregnant women, who are at increased risk of severe outcomes, yet vaccination uptake remains low.
objectiveInvestigate pregnant women's willingness to receive influenza vaccination, identify key influencing factors, and elucidate the pathways shaping this willingness.
methodsA cross-sectional web-based survey was performed. The questionnaire included their socioeconomic characteristics, pregnant status and histories, knowledge of the influenza vaccine, and attitudes toward the seasonal influenza vaccine. A univariate analysis was initially performed to screen potential variables associated with pregnant women's willingness to receive influenza vaccination. Subsequently, a multivariate binary logistic regression model was constructed to assess the independent effects of these variables on vaccination willingness. Additionally, a mediation effect model was developed to analyze the mediating pathways of factors influencing vaccination willingness.
resultsA total of 1231 pregnant women participated in this survey. Five hundred and seventy-one (46.4%) were willing to receive the seasonal influenza vaccine. Multivariate analysis identified five key factors influencing willingness: higher annual income (CNY ≥ 200,000 vs. ≤100,000: OR = 2.65, 95% CI: 1.02-6.85), history of delivery difficulties (OR = 0.10, 95% CI: 0.02-0.62), knowledge about the influenza vaccine (OR = 1.69, 95% CI: 1.28-2.23), supportive attitudes towards vaccination (OR = 13.35, 95% CI: 8.26-21.55), and willingness to pay over 500 yuan for the vaccine (OR = 2.29, 95% CI: 1.23-4.27). Attitudes towards vaccination were partially mediated by vaccine knowledge (β = 0.03, 16% of total effect), with no mediation effects observed for price or delivery history.
conclusionsThis study pinpointed pivotal factors contributing to pregnant women's hesitancy towards seasonal influenza vaccination. Our findings underscore the urgent need for integrating influenza vaccination programs with comprehensive educational and promotional strategies in the future.
