Figure 1 CONSORT
Diagram of Patient Selection
The CONSORT diagram of the patient selection process is illustrated in
this figure. The definition of an intramural hematoma (IMH) is the
absence of an intimal dissection or false lumen flow with the presence
of a circular or crescent-shaped hematoma larger than 5 mm in the aortic
wall. Eligible uncomplicated type B IMH patients who refused further
medical treatments and those without complete imaging records,
laboratory test results and follow-up data were considered as missing
data We used the method of complete-case analysis in which we discarded
these missing data with incomplete information.
