ABSTRACT
SARS Coronavirus-2 is one of the most widespread viruses globally during the 21st century, whose severity and ability to cause severe pneumonia and death vary. We performed a comprehensive systematic review of all studies that met our standardised criteria and then extracted data on the age, symptoms, and different treatments of Covid-19 patients and the prognosis of this disease during follow-up. Cases in this study were divided according to severity and death status and meta-analysed separately using raw mean and single proportion methods. We included 171 complete studies including 62,909 confirmed cases of Covid-19, of which 148 studies were meta-analysed. Symptoms clearly emerged in an escalating manner from mild-moderate symptoms, pneumonia, severe-critical to the group of non-survivors. Hypertension (Pooled proportion (PP) 0.48 [95% Confident interval (CI) 0.35-0.61]), diabetes (PP 0.23 [95% CI 0.16-0.33]) and smoking (PP 0.12 [95% CI 0.03-0.38]) were highest regarding pre-infection comorbidities in the non-survivor group. While acute respiratory distress syndrome (PP 0.49 [95% CI 0.29-0.78]), (PP 0.63 [95% CI 0.34-0.97]) remained one of the most common complications in the severe and death group respectively. Bilateral ground-glass opacification (PP 0.68 [95% CI 0.59-0.75]) was the most visible radiological image. The mortality rates estimated (PP 0.11 [95% CI 0.06-0.19]), (PP 0.03 [95% CI 0.01-0.05]), and (PP 0.01 [95% CI 0-0.3]) in severe-critical, pneumonia and mild-moderate groups respectively. This study can serve as a high evidence guideline for different clinical presentations of Covid-19, graded from mild to severe, and for special forms like pneumonia and death groups.
