SARS-CoV-2 coinfections among pertussis cases identified through the Enhanced Pertussis Surveillance system in the United States, January 2020-February 2023.
Article in PloS one, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundBacterial and viral respiratory coinfections are common, but the prevalence of SARS-CoV-2 infections among pertussis cases has not been estimated. We examine the prevalence and temporality of SARS-CoV-2 infections among pertussis patients and describe pertussis clinical severity among patients with and without SARS-CoV-2 coinfections.
methodsConfirmed and probable pertussis cases among individuals with cough onset between January 1, 2020 and February 15, 2023 were identified through surveillance in seven Enhanced Pertussis Surveillance (EPS) sites. Pertussis cases with a laboratory-confirmed SARS-CoV-2 infection detected within 30 days before or after pertussis cough onset were defined as coinfections. We describe patient demographics, symptoms, and severe complications and outcomes (seizures, encephalopathy, pneumonia, hospitalization, or death) by coinfection status.
resultsAmong 765 pertussis cases reported during the study period, the prevalence of SARS-CoV-2 coinfections was 0.78% [6/765]. Among the six patients meeting the coinfection definition, the majority (83.3% [5/6]) had SARS-CoV-2 infections detected following pertussis cough onset. Compared to those with no known coinfection, a higher proportion of those with coinfections reported severe complications or outcomes (50.0% [3/6] vs. 5.2% [36/694]). DISCUSSION: Although the prevalence of pertussis patients with SARS-CoV-2 coinfections was low, patients with coinfections reported more severe complications and outcomes compared to those with pertussis alone. Given the decline in reported pertussis cases during the COVID-19 pandemic, continued monitoring of pertussis incidence alongside respiratory viral infections will be important as the pertussis burden returns to pre-pandemic levels.
