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

Vaccine mandates were widely implemented against COVID-19, and a large and multidisciplinary literature has emerged as a result, covering fields such as epidemiology, economics, ethics, and law. We compiled an openly available repository of this literature, including 503 studies on COVID-19 vaccine mandates. We identified them through a manual multi-database search and performed the data extraction using a large language model. The dataset stores information, for each study, on the scope and sanctions of the relevant mandate(s), the study design, target population, outcomes, and themes, allowing users to quickly navigate this complex literature. We use the dataset to present key statistical facts and insights about this literature, and we leave to other scholars the opportunity of interrogating it further. As a worked example, we conduct a narrative review of quasi-experimental studies on COVID-19 vaccine mandates. These consistently show short-run increases in first-dose uptake following mandate announcements, with limited evidence on long-run uptake and downstream social, health, and economic outcomes. We provide all data and code to support secondary analyses and future evidence syntheses.
