This looks less than compelling. 

Study participants took pictures of their results and sent them in along with the survey. Poor image quality and file problems made 136 of the results unverifiable. Those 136 were classified as negative results, according to the study.

The number of players involved in the study is unclear. The authors did not ask a question regarding the player population. The Arizona Diamondbacks returned the most samples, with 362, and four teams did not participate.

Also, even if the 0.7% positive rate adjusted for false positives, it's possible that the real number was 0.  That was one of the big problems with the Santa Clara Co. study.  We'd have to see a full report from MLB to know what's up here.
