Cohorts 1 to 4, in which patients were categorized as having a non-high or high probability, were combined for a pooled analysis

, Cohort 3 The third study cohort comprised consecutive patients with suspected DVT or PE who were included in a study evaluating a new latex D-dimer test HemosIL-D-dimer HS 500, Instrumentation Laboratory

Patients were followed up by a clinic visit or telephone contact at the end of 3 months and were instructed to contact their physician if their leg symptoms worsened or if they developed symptoms suggestive of PE

In all studies, the outcome of interest was the development of VTE DVT or PE during 3 months of follow-up in patients in whom DVT was considered excluded after initial diagnostic investigation and who did not receive anticoagulants during follow-up

حاسبة النسبة المئوية المجانية: We then calculated the proportion of patients in whom DVT could be excluded based on a non-high cohorts 1-4 or an unlikely clinical probability cohort 5 together with a normal D-dimer test result — first using the conventional cut-off value, and then using the age-adjusted cut-off value

DVT was ruled out based on: i a non-high clinical probability in combination with a normal D-dimer test result or ii a normal repeated CUS result in patients with a high clinical probability of DVT or an abnormal D-dimer test result — CUS was repeated in patients with normal results on CUS at presentation on days 6 to 8 and days 13-15

Cohort 4 The fourth study was conducted between August 1999 and November 2001 at three hospitals in Ontario, Canada, affiliated with McMaster University in Hamilton

The results and the inclusion and exclusion criteria were published previously

Patients with an intermediate clinical probability of DVT and a normal D-dimer test underwent imaging studies at the treating physician's discretion

30: The study was performed at four hospitals in Bologna Italy , Ottawa Canada , Nice France and Durham South Africa between January 2006 and January 2008

However, we believe that including different study cohorts reinforces the generalizability of our findings

The inclusion and exclusion criteria were published previously

Increasing the D-dimer cut-off value did not compromise safety

The diagnosis of DVT can be safely excluded based on the combination of a low or intermediate clinical probability combined with a negative D-dimer blood test, in which case imaging studies can be avoided

النسبة المئوية: Patients with non-high or unlikely probability of deep vein thrombosis were included in the analysis; four different D-dimer tests were used
30 (عدد): It would, therefore, be preferable to be able to exclude the diagnosis of DVT without the need for CUS, especially in the older population of patients
