Impact of vaccination on electrocardiograms of hospitalized patients for Covid-19.
Article in Vaccine: X, 2023. 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
Introduction: We sought to assess the impact of SarsCov-2 vaccination on admission12-lead electrocardiogram of hospitalized patients. Methods: We retrospectively analyzed and compared admission 12-lead electrocardiograms of all patients hospitalized in dedicated Internal Medicine Unit for Covid-19 both in pre-vaccination period (PV) and after vaccination (V). Results: 667 consecutive Covid-19 in-patients were enrolled in the study: PV hospitalized patients were older (68vs57 years, p < 0.01), had higher rates of atrial fibrillation/flutter (13%vs2.5%, p < 0.01), any arrhythmia (26%vs8%, p < 0.01), and ST-T abnormalities (22%vs7.4%, p < 0.01). Mortality rates in hospitalized Covid-19 patients were higher before vaccination period (20%vs4%, p < 0.01). Minimal vaccination coverage of population (V period) was inversely and independently associated with in-hospital mortality (odds ratio 0.09, 95%CI 0.01-0.68, p < 0.05). Conclusions: SarsCov-2 vaccination campaign and even partial coverage of local population was associated with less frequent abnormalities at admission ECG in hospitalized non-critically hill Covid-19 patients and lower mortality.
