Today we present 23 new placebo and nocebo research papers, comments and abstracts identified during December 2020. As usual, they are based on new PUBMED publication using the search terms „placebo“ and „nocebo“ and are hand-selected from more than 972 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 more than 4,500 relevant papers.
