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; CI: confidence interval; OR: odds ratio; ULN: upper limit of normal.
