What are the limitations of the systematic review?
Many reviews did not provide adequate summaries of the included studies. Settings of test use, the expected role of the test, study design characteristics, and demographics of participants, were often not reported. The counts needed to reconstruct the 2×2 tables of results used in each study were often not provided.
