Barriers to influenza vaccination in older adults with chronic diseases: Insights from a COM-B model-based meta-analysis.

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 study investigated barriers to influenza vaccination among older adults with chronic diseases through a systematic review of 21 studies (391 467 participants, 13 countries) following PRISMA guidelines. According to the COM-B framework, barriers in the capability (OR = 1.47), opportunity (OR = 2.07) and motivation (OR = 1.35) dimensions significantly influenced influenza vaccination behaviors. The strongest predictors included no prior vaccination history (OR = 3.17), exposure to negative vaccine advice (OR = 2.96), and limited healthcare utilization (OR = 2.3). Findings emphasize that structural interventions targeting the opportunity dimension-particularly government-funded vaccination programs- exhibit the greatest potential for improving influenza vaccination coverage. Prioritizing policy-level initiatives over individual-level education campaigns may yield more equitable and sustainable outcomes in this high-risk group.
