Table 1 Comparison of parameters between adverse outcome (+) group and adverse outcome (−) patients in all enrolled patients (mean ± SD)

From: A decision tree built with parameters obtained by computed tomographic pulmonary angiography is useful for predicting adverse outcomes in non-high-risk acute pulmonary embolism patients
