This is a generic protocol that covers two separate reviews. The primary objectives of each review will be the following.
CDR and D-dimer are analyzed as triage tests and will not be directly compared to each other since they are not alternatives but potentially complimentary.
US and MRI are alternatives for the diagnosis of lower-extremity DVT in pregnancy and the postpartum period and will, therefore, be compared for diagnostic superiority if sufficient data are available, as will alternative CDRs.
This is a protocol.
