Immunosuppression and cardiovascular dysfunction in patients with severe versus mild coronavirus disease 2019: a case series.
Article in Clinical & translational immunology, 2020. 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
objectivesAs coronavirus disease 2019 (COVID-19) continues to spread globally, we aimed to describe and compare changes in the immune and cardiovascular systems of patients with mild versus severe COVID-19 at different time points during the course of disease.
methodsOne hundred and one patients diagnosed with COVID-19 who underwent serial peripheral blood collection and chest computed tomography (CT) imaging were enrolled in this study and grouped by the severity of their illness. Changes in the immune and cardiovascular systems were analysed and compared between groups.
resultsThe study included 43 women and 58 men, with a median age of 45 years (interquartile range [IQR], 16-71). We identified spleen shrinkage in 27.7% of study patients. Ratios of spleen volume to patient (skin) volume were compared, with evidence that severe patients had more splenic shrinkage than mild patients. Lymphopenia was observed in 65.3% of patients, and 27.3% of patients had persistently low levels of lymphocytes after discharge. Tachycardia occurred mainly during the first 2 days of hospitalisation, with increases in creatine kinase-myocardial band levels in 10 (9.9%) patients and arrhythmias in 16 (15.8%) patients.
conclusionsIn addition to pulmonary manifestations, our study demonstrated that other organ systems can also be affected during COVID-19 infection, with evidence of immunosuppression and cardiovascular dysfunction, which may contribute to increased mortality rates in critically ill COVID-19 patients.
