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
Coronavirus disease 2019 (COVID-19) has recently broken out in China. To describe the clinical and computed tomography (CT) characteristics in patients with COVID-19-induced pneumonia, the current study retrospectively analyzed the data of 152 patients with pneumonia between December 30, 2019 and February 29, 2020. Pharyngeal swabs for nucleic acid detection of respiratory secretions were used for all patients. A total of 65 cases were diagnosed as COVID-19, and 87 cases were non-COVID-19. When comparing the clinical and CT characteristics of the two groups of patients, only sex and history of exposure presented a statistically significant difference. The normal/low white blood cell count, low lymphocyte ratio and high C-reactive protein (CRP) exhibited a statistically significant difference between the two groups. A total of 62 patients in the COVID-19 group exhibited ground-glass opacity (GGO), which was higher than that in the non-COVID-19 group. In the COVID-19 group, 33 cases presented angiographic thickening in GGO, and 27 cases displayed a paving stone sign, which were higher than those in the non-COVID-19 group. Compared with the non-COVID-19 group, the lesions in the COVID-19 group were principally characterized by bilateral lungs, multifocal and subpleural distribution. The results of the present study revealed that when the male patients with contact history in the epidemic area exhibited fever and cough symptoms, the laboratory tests indicated normal/low white blood cell counts, low lymphocyte ratios and elevated CRP levels. CT scans were recommended for subsequent examination. GGO or GGO and consolidation with bilateral lungs were indicated to be primarily distributed in the multifocal subpleural area and were accompanied by angiographic thickening in GGO and paving stone sign. In conclusion, regardless of whether the viral nucleic acid test is positive, COVID-19 should be considered for medical treatment observation in isolation.
