Effect of Universal Masking on Non-Severe Acute Respiratory Syndrome Coronavirus 2 Healthcare-Associated Respiratory Viral Infections.
Article in Open forum infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Respiratory viral infections are common and are a major cause of morbidity and mortality. We evaluated the impact of universal masking implemented during the coronavirus disease 2019 (COVID-19) pandemic on other healthcare-associated respiratory viral infections (HA-RIs) in an academic medical center. Methods: A retrospective cohort study was performed among all inpatients aged ≥18 years admitted between 1 May 2019 and 30 June 2022. Universal masking was implemented in May 2020 at our hospital and state-level mask mandates had been lifted by May 2021. We evaluated and compared the HA-RI rates, adjusted for monthly community-onset viral infections, during the premasking period, universal masking period, and post-community mandate period. Results: We identified 3015 patients (median age, 58 years; 48.0% males) with a positive respiratory viral test within 14 days prior to, or during, their hospitalization; 441 (14.6%) patients had an HA-RI. Rhinovirus/enterovirus (51.0%), parainfluenza virus (14.3%), coronaviruses (229E, OC43, HKU1, and NL63; 13.2%) and influenza (10.0%) were the predominant HA-RI viruses detected. The monthly HA-RI rate decreased 34.9% (95% confidence interval, 8.8%-51.8%) after the implementation of universal masking (0.71 premasking period vs 0.19 universal masking period vs 0.35 infections per 1000 patient-days in the post-community mandate period) while accounting for a drop in the community-onset respiratory viral infections using a structural time-series model analysis ( Conclusions: Implementation of universal masking at our hospital was associated with a significantly reduced incidence of HA-RIs.
