Liang 2020 COVID-GRAM logistic probability of critical illness (ICU, invasive ve

Liang 2020 COVID-GRAM logistic probability of critical illness (ICU, invasive ventilation, or death) among hospitalized COVID-19 from age, caller-assigned chest radiograph abnormality, hemoptysis, dyspnea, unconsciousness, comorbidity count, cancer history, neutrophil-to-lymphocyte ratio, LDH (U/L), and direct bilirubin (umol/L). Table 3 coefficients. magent does not read the film or count comorbidities. Not a diagnosis or ICU-allocation order.
