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: The sensation of throat closure after vaccination is concerning for anaphylaxis and leads to vaccine hesitancy. Objectives: We characterized patients who developed laryngopharyngeal symptoms (LPhS) after coronavirus disease 2019 (COVID-19) vaccination and assessed risk factors for these symptoms. Methods: The study analyzed data from the COVID-19 vaccines adverse reactions registry (December 14, 2020, to June 13, 2022). Outcomes included the incidence of postvaccination LPhS and use of epinephrine. We identified and compared risk factors for COVID-19 postvaccination reactions between subjects with and without LPhS. Results: A total of 158 subjects were enrolled onto the registry. LPhS were reported in 61 subjects (38.6%), of whom 52 (85.2%) received a subsequent dose. With initial vaccination, the use of epinephrine was higher in subjects with LPhS (20%) compared to those without (6%; Conclusions: In our registry, postvaccination LPhS were common. LPhS can mimic anaphylaxis and lead to more frequent use of epinephrine. Gastroesophageal reflux disease was more frequent in these subjects. Patients with subjective throat closure sensation can safely receive subsequent vaccine doses with close observation and reassurance. LPhS are not unique to COVID-19 vaccines. Patient and provider education regarding the role of gastroesophageal reflux disease as a risk factor for LPhS with vaccination can improve vaccine uptake.
