Chest computed tomographic findings of patients with COVID-19-related pneumonia.
Article in Acta radiologica open, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundIn December 2019, pneumonia cases of unknown cause were announced in Wuhan, China. The causative agent of pneumonia was identified as coronavirus 2 (SARS-CoV-2), and the disease was named coronavirus disease 2019 (COVID-19). PURPOSE: To evaluate the usefulness of computed thoracic tomography (CT) and postero anterior (PA) thoracic radiography in patients with COVID-19. MATERIAL AND
methodsBetween March and June 2020, the patients who arrived at our hospital with suspicion of COVID-19 were retrospectively analyzed. Thorax CT findings of the 281 patients (142 females and 139 males; age range 3-91 years) with positive PCR tests were evaluated. Lesions in the lung parenchyma were examined according to their number, localization, and distribution. PA chest radiograms were classified into two groups, positive and negative for the lung parenchymal lesions.
resultsOf the total 281 patients with PCR-positive COVID-19, CT examinations were normal in 107 (38.1%), and positive CT findings for pneumonia were found in 174 patients (61.9%). Bilateral involvement was observed in 100 (57.5%) of the 174 patients with positive CT findings, and unilateral involvement was observed in 74 (42.5%) of them. According to the localization of the lesions, peripheral subpleural distribution occurred in 160 of the 174 patients (91.9). The most common lesion was the ground glass opacities (GGO). In 77 of 281 PCR-positive patients (27.4), pulmonary lesions were found on PA chest radiograms.
conclusionThe presence of bilateral posterior subpleural GGO, nodule, and consolidation in thoracic CT are significant in terms of COVID-19 pneumonia.
