AUC, Area under the curve; Caprini[COVID-19:adm], considering two points for asymptomatic infection, three points for symptomatic infection, five points for symptomatic infection with positive D-dimer, score assessed at admission; Caprini[COVID-19:fin], considering two points for asymptomatic infection, three points for symptomatic infection, five points for symptomatic infection with positive D-dimer, score assessed at discharge or death; Caprini[Dd>3ULN:adm], considering three points if D-dimer increased >3 times over ULN, score assessed at admission; Caprini[Dd>3ULN:fin], considering three points if D-dimer increased >3 times over ULN, score assessed at discharge or death; Caprini[Dd>ULN:adm], considering three points if D-dimer increased over ULN, score assessed at admission; Caprini[Dd>ULN:fin], considering three points if D-dimer increased over ULN, score assessed at discharge or death; Caprini[orig:adm], the original score assessed at admission; Caprini[orig:fin], the original score assessed at discharge or death; SD, standard deviation; ULN, upper limit of normal.
