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

Promotion of COVID-19 vaccination requires understanding its determinants, an important one of which is outcome expectancy. However, reliable and valid measurement tools are absent. This study thus developed and validated an Outcome Expectancy Scale for COVID-19 Vaccination (OES-COVID-19). An inductive approach was used for scale development; content validity of the items was then assessed by an independent evaluation expert panel. Iteratively, 17 scale items were created and validated in a population-based telephone survey conducted among 500 adults of the general population in Hong Kong, China, from August to September 2021. Using half of the sample (
