COVID-19 Mitigation With Appropriate Safety Measures in an Essential Workplace: Lessons for Opening Work Settings in the United States During COVID-19.
Article in Open forum infectious diseases, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundNonpharmaceutical interventions (NPIs) mitigate coronavirus disease 2019 (COVID-19). Essential workplaces remained open during COVID-19, but few US-based settings detail outcomes.
methodsMercury Systems is a US-based manufacturing company that remained open during COVID-19. NPIs-distancing, masking, hand hygiene, ventilation-were successively deployed from March to August 2020. The company expanded sick leave, asked employees to report work outages from illness, and administered employee satisfaction surveys. Three sites in Arizona, Southern California, and New Hampshire administered testing campaigns via reverse transcription polymerase chain reaction (PCR) of nasal swabs in late July to early August for all employees at work or at home self-isolating due to symptoms. Descriptive statistics summarized findings.
resultsAmong 586 employees at 3 sites, only 1.5% employees developed severe illness over the study duration. Testing campaigns revealed 44 with positive PCR results at a cycle threshold (CT) <37 (likely infectious) and 61 with a CT ≥37 (low-level viral load). True positivity rates were consistent with community prevalence at the time: 1.1% in New Hampshire, 6.2% in California, 12.9% in Arizona. Of all employees with positive tests, 99% were asymptomatic. Employee surveys showed high satisfaction.
conclusionsIn a multisite US company that instituted NPIs for COVID-19 mitigation, the proportion of asymptomatic COVID-19 infections on surveillance testing was high (99%). Although surges in community transmission were seen in 2 sites during the study, employee prevalence reflected community prevalence, despite daily workplace presence. This study demonstrates that NPIs likely mitigate severe COVID-19 illness, that PCR tests should incorporate CT values, and that expanded sick leave likely encourages self-isolation, suggesting strategies for work re-openings.
