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
introductionCoronavirus disease 2019 (COVID-19) pandemic has engulfed the world, within a short span of time crippling many health systems. The disease in its ever-evolving course is exhibiting a myriad of symptoms and imaging manifestations. This retrospective study was conducted to generate evidence from the chest computed tomography (CT) findings of patients with COVID-19 pneumonia to aid in the diagnosis and disease management.
methodsThis retrospective study included all patients with reverse transcriptase polymerase chain reaction confirmed COVID-19 disease who underwent chest CT between 1
resultsThe common presenting clinical symptoms were fever, cough, myalgia and sore throat. The most frequent CT imaging feature consisted of ground-glass opacities (GGOs), consolidation and crazy paving distributed bilaterally, peripherally in subpleural location with a predilection for the posterior parts of lungs. Reverse halo sign was observed in 12 patients and halo sign in 3 patients. Dilated pulmonary vessels with mild bronchiolectasis were observed in the involved lung parenchyma. Less common findings included pleural effusion, mediastinal lymphadenopathy, and pericardial effusion. The mean CT severity score gradually increased with increasing age.
conclusionThe predominant imaging finding of COVID-19 pneumonia was peripheral GGO's distributed bilaterally in peripheral subpleural region and having predilection for the posterior parts of the lungs which gradually evolve into organizing pneumonia patterns. Although COVID-19 shares imaging findings with other viral pneumonias, however in the context of the current pandemic, we must keep COVID-19 a differential diagnosis, in all patients with fever and respiratory symptoms.
