In the original publication of the article, the second sentence in second paragraph under the heading “What are the symptoms characteristic of severe COVID-19?” in page 4, should read as “Patients with severe COVID-19 had a significantly higher incidence of abdominal pain than those non-severe illness (OR 2.70; [95% CI 1.17–6.27; p = 0.02; I2 = 0%]) (Fig. 2).”

In Table 2, the value of “Effect estimate” for “2.4 Vomiting” should read as “0.53 [0.31, 0.92]”.
