Relationship between the computed tomography pattern and vaccination status in individuals with COVID-19.
Article in Radiologia brasileira. 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
Objective: To evaluate the frequency of the typical computed tomography (CT) pattern in individuals with coronavirus 2019 (COVID-19), comparing those who were vaccinated with those who were unvaccinated. Materials and Methods: This was a retrospective study of the medical records of patients with clinical suspicion of COVID-19 between August 2021 and February 2022. The vaccination status was classified as absent/incomplete (0 or 1 dose) or complete (2 or more doses). The pattern seen on the first chest CT was defined as typical, atypical, indeterminate, or normal, the last three patterns being combined to form what was designated the non-typical group. Results: Binary logistic regression analysis showed that individuals with a complete vaccination status were less likely to present with the typical CT pattern than were those with an absent/incomplete vaccination status (adjusted OR = 0.19, 95% CI: 0.06-0.60). Conclusion: This information is important because it demonstrates that the frequency of the CT pattern considered typical of COVID-19 is currently lower than it was before the vaccines became available. Therefore, the typical CT pattern is no longer expected.
