Figure. 2 Time to Clinical Improvement analysis in different D-Dimer
levels when anticoagulant therapy was initiated. The differences of
improvement in two groups were observed both within 7 days (P=0.24) and
14 days (P=0.03).
Figure. 3 The time to the first appearance of improvement with chest CT
and patients’ hospital stays between two groups. The mean days at the
time of CT imaging improvement were 12.1±3.6 days in the group of
D-Dimer≤3, while 16.2±6.4 days in D-Dimer>3 (p=0.028). The hospital
stays in the two groups were 27 (25.5-30.5) days and 28 (27-36.5) days
separately (p=0.086).
