Clinical and laboratory findings of COVID-19: A systematic review and meta-analysis.
Synthesis in Journal of the Formosan Medical Association = Taiwan yi zhi, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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.
Who cites it
9 citing papers in PubMed, 1 synthesis or guideline pooled it.

Abstract
background/purposeThe aim of this study was to systematically review all COVID-19 publications to summarize the clinical features, assess comorbidities, prevalence, and disease outcomes.
methodsIncluded were all COVID-19 published studies between January 1 to July 20, 2020. The random effect model was used to calculate the pooled prevalence and corresponding 95% confidence interval (CI). Publication bias was assessed using the funnel plot for the standard error by logit event.
resultsThe mean age of the patients was 46.8 years (95% CI, 41.0-52.6) and males comprised 54.0% (95% CI, 51.3-56.7). Total co-morbidities prevalence was 29.5% (95% CI, 19.0-36.6), with diabetes mellitus being the most prevalent 13.8% (95% CI, 8.7-21.1), followed by hypertension 11.7% (95% CI, 5.7-22.6), and cardiovascular disease 9.7% (95% CI, 6.5-14.2). The most common clinical manifestations were fever, 82.0% (95% CI, 67.7-90.8), cough 54.3% (95% CI, 45.5-62.9), fatigue 30.2% (95% CI, 23.3-38.1), sputum 28.5% (95% CI, 21.2-37.2), sore throat 21.7% (95% CI, 14.6-31.0), and headache 11.0% (95% CI, 7.9-15.2). The most common COVID-19 serious complications were RNA Anemia 98.2% (95% CI, 96.2-99.2), hospitalization 83.7% (95% CI, 76.0-89.3), bilateral pneumonia 70.9% (95% CI, 58.2-81.0); of those hospitalized 43.5% (95% CI, 24.9-64.2) were discharged. Fatality accounted for 10.5% (95% CI 6.8-16.1).
conclusionPatients infected with COVID-19 coronavirus showed a wide range of clinical presentation with non-specific symptoms.
