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

backgroundThe global COVID-19 pandemic has impaired the health and living conditions of millions of people. For governments to formulate policies promoting vaccination behavior, it is important to understand individuals' intentions to vaccinate. This study explores the effectiveness of a brief online intervention based on the Health Action Process Approach (HAPA) in improving individuals' COVID-19 vaccination intention, as well as considering the reasons for their unwillingness to get vaccinated.

methodA total of 1,258 participants were assessed using a questionnaire to determine their phase of vaccination intention (pre-intention, intention, and action). Subsequently, focused on the underlying factors in the pre-intention phase (i.e., task self-efficacy, outcome expectation, and risk perception), a 7-day randomized controlled HAPA intervention (n

resultsThe intervention may effectively improve participants' COVID-19 vaccination intentions; however, it had no impact on their planning and actions involved in taking the vaccine.

conclusionsThis study provides relevant reference data for government stakeholders to use in developing public awareness campaigns and policies to encourage COVID-19 vaccination.
