Fig. 4From: Automated left atrial strain analysis for predicting atrial fibrillation in severe COVID-19 pneumonia: a prospective studyC-statistic and receiver operating characteristics curve (ROC) of factors associated with the occurrence of AF. The ROC curve analyzed the discrimination ability of the model composed of LAScd and SOFA cv > 1 to predict AF. AF: atrial fibrillation; AUC: area under curve; CV: cardiovascular; ROC: receiver operating characteristic curve. SOFA: sequential organ failure assessmentBack to article page
