Paxlovid-Induced Symptomatic Bradycardia and Syncope.
Article in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
Paxlovid (nirmatrelvir/ritonavir) is a game changer in the fight against COVID-19 due to its ease of administration and significant benefits of reducing progression to severe COVID-19, hospitalization, and death. Cardiac adverse events such as bradycardia and syncope are not known with this medication. We report a case of a 71-year-old patient who developed symptomatic bradycardia, syncopal episodes, and sinus pause after taking Paxlovid. Discontinuing medication and intravenous atropine helped to reverse the bradycardia and symptoms promptly. She did not require a pacemaker. We would like to report this possible association between Paxlovid and bradycardia. Until further information or studies are available, it is advised to promptly discontinue Paxlovid after any evidence of bradycardia and closely monitor for at least 40 hours in a hospital setting. The reported half-life (t 1/2) of the medication is 6.05 ± 1.79 hours and using 8 hours as a reference for the upper limit of t 1/2, around 97 % of the medication should be cleared off in about 40 hours (five half-lives).
