This is old news, but still necessary to know...

 

" Research conducted in certain countries was uniformly favorable to

acupuncture; all trials originating in China, Japan, Hong Kong, and Taiwan

were positive, as were 10 out of 11 of those published in Russia/USSR>

....

The results for China, Japan, Russia/USSR, and Taiwan were 99%, 89%, 97%,

and 95%, respectively. No trial published in China or Russia/USSR found a

test treatment to be ineffective. Conclusions: Some countries publish

unusually high proportions of positive results. Publication bias is a

possible explanation. Researchers undertaking systematic reviews should

consider carefully how to manage data from these countries. "
