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
objectivesDuring the height of the COVID-19 pandemic, vaccine hesitancy in the United States was a key driver of continued COVID-19 transmission and the emergence of new variants. We examined the effect of a mandate that required patrons at nonessential venues (eg, restaurants, bars) in New Orleans, Louisiana, to be vaccinated to enter these establishments from August 2021 through March 2022.
methodsWe implemented a parish-level synthetic control model that compared vaccination trends in Orleans Parish (county) (the boundaries of Orleans Parish are equivalent to the city of New Orleans) with a synthetic composite of other parishes in Louisiana that had similar vaccination trends before the mandate. We used permutation testing (ie, shuffle testing) to determine the significance of differences in vaccination rates between Orleans Parish and other parishes.
resultsIndividuals in Orleans Parish initiated an average of 760 more vaccines weekly during the 31 weeks in which the mandate was in place, which was significantly higher than expected based on the synthetic control (
conclusionsThe rate of vaccine initiation increased during the vaccine mandate for nonessential venues. Implementing such mandates may be an effective intervention in overcoming COVID-19 vaccine hesitancy during a future pandemic.
