1 · What the graph read from it

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.

2 · The registry

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: Six years after the emergence of SARS-CoV-2, vaccination remains still central to preventing severe COVID-19. The aim was to determine the impact of the vaccine type and number of doses on the course of COVID-19 infection among Polish healthcare professionals. Methods: From November 2021 to February 2022, 813 people took part in a survey, including 625 women (76.9%) and 188 men (23.1%). Results: 743 respondents (91.39%) had no confirmed COVID-19 infection after taking one of the available vaccines. However, there was no significant relationship between the number of doses of the SARS-CoV-2 vaccine and the occurrence of coronavirus infections after their administration ( Conclusion: The type of preparation taken did not affect the re-infection with the coronavirus, its course and the risk of complications. Vaccinated people were significantly less likely to be hospitalized due to COVID-19. There was no significant relationship between the number of doses of the SARS-CoV-2 vaccine and the occurrence of COVID-19 after their administration.
