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
introductionDuring the outbreak of the COVID-19 pandemic, radiological examinations became crucial in assessing the severity and progression of lung injuries in COVID-19 patients.
aimThis study was done to identify radiological patterns of lung injuries in COVID-19 patients, assess lobar involvement, and perform CT severity scoring on symptomatic patients on a baseline scan. METHODS AND MATERIAL: All the RT-PCR-positive patients were retrospectively enrolled in the study from August 16, 2020 to October 12, 2020. The final heart-resolution computed tomographic (HRCT) thorax data of a total of 119 COVID-19 patients was analyzed using simple statistical methods. A p-value of less than 0.05 (p < 0.05) was considered statistically significant.
resultsA total of 119 HRCT thorax scans of symptomatic indoor RT-PCR-positive patients were reviewed. Over 50% of the patients were under 50 (n = 66; 25 = 5; 25-50 = 61). Males > females: 3.25:1 (M = 91; F = 28). Peripheral involvement dominated (n = 90). Both lungs were affected equally, but the right lower lobe was more involved (n = 103) than the left (n = 98). Inpatient care was needed for 64.70% of CT severity score (CTSS) 10 COVID-19 patients (n = 77). Most positive CT scans (n = 115) revealed ground glass opacities (n = 112; 97.39%). Vascular dilatation or vasculitis (n = 65; 56.62%) and organizing pneumonia-like changes (n = 61; 53.04%) were also common. Vascular enlargement (56.53 percent, n = 65) and reverse halo (52.17%, n = 60) were the most common CT signs.
conclusionThe most common chest CT finding in COVID-19 was ground-glass opacity in peripheral distribution with extensive lung involvement. These ground glass opacities may coalesce into consolidations. Vascular dilatation, organizing pneumonia, interlobular septal thickening, and crazy paving were other important imaging characteristics.
