The circulation of Non-SARS-CoV-2 respiratory viruses and coinfections with SARS-CoV-2 during the surge of the Omicron variant.
Article in Journal of clinical virology : the official publication of the Pan American Society for Clinical Virology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundIn December 2021, the SARS-CoV-2 Omicron variant displaced the Delta variant and caused an unprecedented spike in the numbers of COVID-19 cases. This study reports the positivity rates of circulating non-SARS-CoV-2 respiratory viruses and evaluates coinfections of these viruses with SARS-CoV-2 during the Omicron surge.
methodsData from the multiplex respiratory panels used for diagnosis at the Johns Hopkins Microbiology Laboratory were used to assess positivity rates and respiratory virus coinfections in the time frame between November 2021 and February 2022. Clinical presentations and outcomes were assessed in the cohort of 46 patients who had SARS-CoV-2 coinfections with other respiratory viruses.
resultsBetween November 2021 and February 2022, the high positivity of SARS-CoV-2 outcompeted enterovirus/rhinovirus and other circulating respiratory viruses and was associated with a notable decrease in influenza A infections. Coinfections represented 2.3% of the samples tested by the extended multiplex respiratory panel. SARS-COV-2 coinfections represented 25% of the coinfections in this time frame and were mostly SARS-COV-2/enterovirus/rhinovirus. Of the SARS-CoV-2 coinfection cohort, 3 patients were hospitalized and were coinfected with influenza-A (2) or RSV (1). Cough and shortness of breath were the most frequent symptoms (29%) followed by fever (28%).
conclusionsThe SARS-CoV-2 Omicron surge was associated with a change in the circulation of other respiratory viruses. Coinfections were most prevalent with viruses that showed the highest positivity in this time frame.
