Sinus Arrest Associated With a COVID-19 Nasopharyngeal Swab Procedure: A Case Report.
Article in Cureus, 2026. 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
During the COVID-19 pandemic, nasal swabs became a routine test for infection. This non-invasive procedure is typically regarded as benign and rarely associated with complications. However, physical stimulation of the nasopharynx and trigeminal nerve can trigger the trigeminocardiac reflex (TCR), a vagally mediated cardioinhibitory response that can lead to sinus arrest. In this study, a clinical trial participant experienced a 3.4 s episode of sinus arrest which was captured on electrocardiogram telemetry during a routine COVID-19 nasal swab test. Diagnosis of the TCR was based upon the plausibility and reversibility criteria, which are hallmarks of this condition. Healthcare providers need to be aware of this phenomenon as well as other potential complications when performing nasopharyngeal swabs.
