The Limits of the Probiotic Intervention

The authors reported as well that they didn't find a difference in the average level of psychiatric symptoms measured when they assessed them at monthly visits. The results are quite strong for the probiotic, we know very little else around anything else in terms of the patient's circumstance. I think overall it is still one of the better studies in this area, but it has these couple of limitations that makes you then left with more questions as to why there was such a pronounced reduction in risk over 24-week period.
