Abstract:
[Objective] To assess the diagnostic criteria in literatures of blood-stasis syndrome based on evidence-based medicine. [Methods] The reports on blood-stasis syndrome published in the years of 1978 ~ 2002 were collected and evaluated according to the evidence-based medicine principles. Main outcomes include design method, sample screening, sample size, establishment of control group, randomization, blind method, criteria of diagnostic trials. [Results] In the reports collected, no gold standard and independent blind method were adopted, criteria of diagnostic trials such as sensitivity, specificity and likelihood ratio were incomplete and there was no descriptions of potential bias controlling. As for the literatures sharing the same diagnostic criteria of blood-stasis syndrome, their conclusion did not totally accord with each other. [Conclusion] Diagnostic criteria of blood - stasis syndrome are incomplete and need to be improved. The conclusion in published reports on diagnostic criteria of blood-stasis syndrome will be further verified.
