  1. Data are no. (%) unless specified otherwise. Denominators indicate data lacking for 53 patients. Abbreviations: OR, Odds ratio; CI, confidence interval; IQR, interquartile range; qSOFA, quick sepsis-related organ failure assessment; CT, computed tomography
  2. aLaboratory-based confirmation of 2019-nCoV pneumonia was done by SARS-CoV-2 RNA detection using a well-established RT-PCR assay [9]
  3. bAccording to multivariable logistic regression model analysis (see text for details)
  4. cIncludes anemia, endocrine disorders, inflammatory bowel disease, and obesity
  5. dCT findings in all 112 patients were assessed according to imaging features described elsewhere [10]
  6. eNot calculated because the relative variable was not entered into multivariable logistic regression model (see text for details)
  7. fPatients were admitted between 3/6/2020 and 3/31/2020, with follow-up through 4/23/2020
