  1. # P values were generated by either Mann-Whitney or chi-squared test.
  2. * Intensive care unit (ICU) and hospital mortality outcome of CORE cohort was available only in 2031 and 2010 cases, respectively.
  3. APACHE = Acute Physiology and Chronic Health Evaluation; IQR = interquartile range; SD = standard deviation.
