Diagnostic tests for pregnancy-related deep vein thrombosis

This is a generic protocol that covers two separate reviews. The primary objectives of each review will be the following.

Review one:

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.

Review two:

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.
