I very much agree, we have to be cautious with our optimism. Concerning the approach, this study looked into a fairly new form of rTMS, namely iTBS. Here is paper detailing how it differs from 10Hz rTMS, with a specific focus on potential cost savings: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6742475/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6742475/ We certainly need more data on iTBS effectiveness and I hope that a properly controlled, double-blind study can yield some information on whether this is actually effective on a larger scale and in the long term. A sample size of 21 is simply to small to make any judgement on that.
