They were very heterogeneous regarding study type and size, treated conditions, treatments, measured outcomes, and quality.

Possible publication bias.

Conclusions.

The number of clinical trials on TM available in the West is small; methods and results are heterogeneous.

Implications of Key Findings.

Higher quality larger trials are needed, as is a general overview of traditional usage to inform future clinical trials.
