“From the rebuttal: "Professor Frass has repeatedly stated that his published criticism of the Lancet meta-analysis has never been refuted, and therefore homeopathy is a valid therapy. The last time we heard him say this was during a TV discussion (March 2018) where he said that, if one succeeded in scientifically refuting the arguments set out in his paper, one would show the ineffectiveness of homeopathy." - Norbert Aust”
