Comparative Evaluation of the Clinical Severity of COVID-19 of Vaccinated and Unvaccinated Patients in Southeastern Romania in the First 6 Months of 2022, during the Omicron Wave.
Article in Healthcare (Basel, Switzerland), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
(1) Background: The pandemic wave produced by SARS-CoV-2 Omicron was characterized by milder clinical forms and high contagiousness. The vaccination rate against COVID-19 in Romania was approximately 42%. (2) Objectives: Comparison of the clinical severity in vaccinated patients compared to unvaccinated ones. (3) Methods: A retrospective cohort study was conducted on a group of 699 adult patients confirmed with COVID-19 who presented in the "Sf. Cuvioasa Parascheva" Infectious Diseases Clinical Hospital of Galati, Romania, between 1 January 2022 and 30 June 2022. The study compared the need for hospitalization, reinfections, demographic and comorbidity data, clinical and paraclinical parameters from the initial evaluation, and the ratio of unfavorable developments on subgroups chosen according to the vaccination status. (4) Results and Conclusions: Our study reveals that unvaccinated patients required hospitalization in 54.68% of cases, while fully vaccinated patients had a hospitalization rate of 40.72%, which was significantly lower than that of the unvaccinated group (
