SARS-CoV-2 Infection Among Nursing Home Healthcare Workers: A Longitudinal Study in North-Eastern Italy.
Article in Influenza and other respiratory viruses, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDuring the pandemic, a surveillance program to monitor COVID-19 infection among healthcare workers was established in Friuli Venezia Giulia Region (FVG), Italy. The aim of our study was to measure the risk of acquiring SARS-CoV-2 infection among nursing home employees by job title.
methodsFrom March 1, 2020, to March 31, 2023, a retrospective population-based longitudinal study was conducted in 8880 nursing home employees. For each employee, all swabs up to the first positive result (n = 211.534) were considered. The study period was divided in six phases based on epidemic waves. Generalized estimated equations method for longitudinal binary data was applied with a time lag of a month, in each phase, obtaining an odds ratio (OR) and 95% confidence limit (95% CI) for each job category.
resultsIn Phase 1 (1.3.2020-30.6.2020), compared with administrative assistants, jobs with high patient contact were at increased risk of infection: The OR and 95% CI were 3.52 (1.44-8.56) and 2.96 (1.15-7.66) in healthcare elementary occupation and physicians/nurses, respectively. Corresponding associations in Phase 2 (1.7.2020-31.1.2021) were 1.54 (1.18-2.02) and 1.41 (1.04-1.91). On the contrary, in Phase 6 (20.12.2021-31.3.2023) physicians/nurses were at a decreased risk (0.73 [0.58-0.91]).
conclusionsIn nursing homes, the risk of COVID-19 infection varied by job title and pandemic phase. Virus higher infectivity, probability of closer contact, and better adherence to infection prevention control may explain part of these differences. Stronger nursing home-specific surveillance in patients and employees should be extended worldwide to control this high global burden of disease communities.
