Clinical pre-test probability adjusted versus age-adjusted D-dimer interpretation strategy for DVT diagnosis : A diagnostic individual patient data meta-analysis
Background: To increase the clinical usefulness of the D-dimer test in diagnosis of deep vein thrombosis (DVT), two strategies have been proposed: the age-adjusted, and the clinical pre-test probability (CPTP) adjusted interpretation. However, it is not known which of these strategies is superior. Objective: To conduct an individual patient data (IPD) meta-analysis that compares the sensitivity, s
