Note: APACHE II = Acute Physiology and Chronic Health Evaluation score, CHD = coronary heart disease, CKD = chronic kidney disease, COPD = chronic obstructive pulmonary disease, COVID-19 = coronavirus disease 2019, P25 = 25th percentile, P75 = 75th percentile, SOFA = Sequential Organ Failure Assessment score.
↵* Unless otherwise defined.
↵† We defined the onset of illness as the onset of typical symptoms related to COVID-19, such as fever, dry cough and dyspnea.
↵‡ The SOFA and APACHE II scores were used to assess organ dysfunction and disease severity. Higher scores indicate a higher rate of organ failure and mortality. We calculated these scores from the data of only 64 patients.
