Determinants of influenza vaccine preferences among community-dwelling older adults residents: a discrete choice experiment in Shihezi, China.
Article in BMC geriatrics, 2026. 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
backgroundInfluenza vaccination among the older adults can effectively prevent influenza infection and reduce the outbreak of influenza and influenza-like diseases. This study examined the preferences and heterogeneity of preferences among community-dwelling older adults for influenza vaccines and key attributes of the vaccination process. We aimed to inform the development of demand-driven influenza vaccination strategies.
methodsUsing a multi-stage cluster sampling approach, 654 older residents of Shihezi City, China, were surveyed. Preferences for influenza vaccination attributes were assessed with a mixed logit model to estimate relative attribute importance, willingness to pay, and heterogeneity across sociodemographic and health-related characteristics.
resultsRespondents consistently favored vaccines characterized by a lower incidence of adverse events, high protection rates, and lower out-of-pocket costs. Acceptance was greater when perceived disease severity was high and when vaccination was delivered within the community. The relative importance of vaccine attributes was as follows: incidence of non-serious adverse events (32.38%), protection rate (32.28%), vaccination site (18.54%), disease severity (11.75%), and incidence of serious adverse events (5.06%). Participants were willing to pay and additional 176.50 yuan and 391.00 yuan to reduce the incidence of non-serious adverse events from 50% to 20% and 10%, respectively. Substantial preference heterogeneity was observed by sex, marital status, education attainment, and self-rated health status.
conclusionVaccine safety and effectiveness are pivotal detriments of influenza vaccination decisions among community-dwelling older adults. Tailoring vaccination strategies to reflect these preferences, and to account for subgroup differences, may improve influenza vaccination rates in this population.
