Global COVID-19 vaccine hesitancy among elderly: A systematic review.
Review in Vaccine: X, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Background & Objectives: Elderly infected with COVID-19 has high mortality risk, and the protection from COVID-19 vaccine is limited by vaccine hesitancy. The information of vaccine hesitancy in elderly is incomplete and fragmented. In this study, we attempt to examine the level of vaccine hesitancy in elderly and the related factors in global perspectives. Methods: A systematic review was conducted to include observational studies of COVID-19 vaccine hesitancy in elderly from January 2020 to September 2021. Search strategies covering COVID-19 vaccine, vaccine hesitancy and elderly in four databases of PUBMED, MEDLINE, EMBASE and COCHRANE LIBRARY were adopted. Studies reporting COVID-19 vaccine hesitancy prevalence in elderly were included. A meta-analysis of the vaccine hesitancy prevalence was performed. The primary outcome is the vaccine hesitancy prevalence in elderly population globally. The secondary outcomes are the factors of COVID-19 vaccine hesitancy among elderly. Results: Initial 479 articles were included for screening, with 54 studies included for meta-analysis of COVID-19 vaccine hesitancy in elderly and 6 studies included for qualitative analysis of factors for vaccine hesitancy. The overall prevalence of vaccine hesitancy was 27.7 % (95 % C.I: 23.8-31.6 %). The prevalence was significantly higher in Asia than in Europe (35.3 % VS 17.9 %, p < 0.05). The vaccine hesitancy was significantly higher before the launch of the vaccine than after (30.3 % VS 18.7 %, p < 0.05). Important factors of vaccine hesitancy in elderly identified were low income, low education, perception of COVID-19 being more contagious, more vaccine side effects and lower vaccine efficacy. Conclusions: COVID-19 vaccine hesitancy is an important problem in elderly, with geographical variation. Tailored policy and strategies targeting the hesitancy factors were required to promote COVID-19 vaccine to elderly.
