1 · What the graph read from it

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.

2 · The registry

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

backgroundLow influenza vaccination rates were observed in Asian countries including China. This study investigated the updated seasonal influenza vaccination rates among Chinese in Hong Kong, and the barriers and enablers to vaccination.

methodsEight focus groups were conducted among the Chinese general public, followed by a telephone survey between March and April 2018 with 2,452 respondents (response rate 41.4%).

resultsOf the survey respondents, 29.1% had received influenza vaccine in the past 12 months. A majority of them agreed with 'enhancing immunity' (94.4%) and 'feeling safer' (92.3%) as their reasons for vaccination, followed by the belief on 'quicker recovery' if they had influenza (69.5%), and free/subsidized vaccine (53.8%). Among respondents who had not received influenza vaccine, 71.2% 'believed in the strength of their own immunity' and 65.6% perceived 'low-risk of getting influenza'. Less than half were 'worried about side-effects' and 'effectiveness'. The groups aged 65-74 and 75 or above had vaccination rates of 49.1% and 69.9%, respectively, in contrast to 13.9% for the group aged 18-64. A rate of 37.9% for children was reported by the 442 respondents having children.

conclusionsThe high uptake of vaccines among the children and elderly suggests the positive impact of the subsidy and outreach programs. However, young and middle-aged adults tend to believe in the strength of their own immunity and underestimate the infection risk. Public education should emphasize that inactivated vaccines such as influenza vaccines work by means of the viral antigens stimulating the host's immune system toward the major types of seasonal influenza.
