Public Health Travel Restrictions Implemented for Persons at Risk of Transmitting SARS-CoV-2 Infection-United States, January 1, 2020-April 6, 2022.

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
contextFederal public health travel restrictions (FPHTR) in the United States are implemented for persons who meet specific criteria to prevent spread of communicable diseases of public health concern. FPHTR can mitigate the risk of disease transmission during air travel and mitigating disease translocation between geographic areas.
objectiveTo characterize and determine the extent of FPHTR implementation during the COVID-19 pandemic.
designSecondary data analysis. SETTING AND
participantsThis report reviewed the U.S. public health response for 3010 persons traveling within, into, and out of, the U.S. who were placed on federal public health travel restrictions during the COVID-19 outbreak from January 1, 2020 to April 6, 2022.
main outcome measureTotal number and characteristics of persons with SARS-CoV-2 infection or high-risk exposure added to FPHTR.
resultsDuring this period, FPHTR were implemented for 3010/5460 (55%) persons who were reported to CDC as having tested positive for SARS-CoV-2, or being identified as close contacts of a person with COVID-19, with intention to travel. Of those added to FPHTR lists, 2023/3010 (67%) had confirmed SARS-CoV-2 infection, 975/3010 (32%) were close contacts, and 12/3010 (0.4%) were reasonably believed to have COVID-19 but later confirmed to have another diagnosis and removed. Twenty-six percent (793/3010) of SARS-CoV-2-related FPHTR were for persons reported to CDC after testing positive for SARS-CoV-2 at a testing site located within a U.S. airport.
conclusionsThe extensive application of FPHTR for more than 3000 persons over a period of 29 months during the COVID-19 pandemic was unprecedented. The additional use of FPHTR required extraordinary effort and collaboration among CDC staff and local/state public health agencies for case investigation, reporting, exchange of information, and communication with travelers for case management. Use of this tool should be considered within the context current transmission risk and disease severity.
