Today we present 26 new placebo and nocebo research papers, comments and abstracts identified during November 2021. As usual, they are based on new PUBMED publication using the search terms „placebo“ and „nocebo“ and are hand-selected from more than 1038 new publications during the preceding month. Previously published monthly updates can be found in our archive. Todays selection as well as all previously identified papers will also go into our placebo research library that currently contains nearly 5,000 relevant papers.
