Data from selected trials are summarized in a global meta-analysis and also in subgroups meta-analysis, according to the fact that the user of POC device is the patient himself, with or without personal treatment adaptation, the general practitioner or a health professional in an anticoagulation clinic. Results of the global meta-analysis show a reduction of major thromboembolism and all causes mortality but not of major hemorrhage. Subgroup analysis shows that most favorable results are obtained when patient himself realizes the test and adapts the treatment. Results are compared with those of other published meta-analysis and the limits of results' validity are discussed.
