Predictive factors of hesitancy to vaccination against SARS-CoV-2 virus in young adults in Spain: Results from the PSY-COVID study.
Article in Vaccine: X, 2023. 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
Widespread population vaccination against the SARS-CoV-2 virus is a matter of great interest to public health as it is the main pharmacological measure to contain the COVID-19 pandemic. Hesitancy/reluctance to vaccination has become a main barrier to containing the pandemic. Young adults are the age group with the greatest resistance to vaccination, even in countries with the highest vaccination rates during this pandemic. The objective of this study was to identify the main predictive factors of vaccination intention and profile people with hesitancy/reluctance to vaccinate against SARS-CoV-2 virus in young adults living in Spain during the pandemic. A cross-sectional study was conducted based on the administration of an online survey (PSY-COVID-2) that evaluated the intention of vaccination together with a wide range of sociodemographic, social, cognitive, behavioral and affective variables in a sample of 2210 young adults. 14% of the sample showed hesitancy/reluctance to vaccination at the beginning of their vaccination campaign. A total of 35 factors were associated (small to medium effect sizes) with the intention to get vaccinated. A reduced set of 4 attitudinal and social variables explained 41% of the variability in vaccination intention: attitude to the vaccination, trust in health staff/scientists, conspiracy beliefs about SARS-CoV-2 and time spent being informed about COVID-19. These variables showed good sensitivity/specificity for classifying people as reluctant/not reluctant to vaccination, properly classifying 86% of people. Psychosocial processes related to attitudes, trust and information are the main predictors of vaccination intention in a highly reluctant group such as the young adult population.
