Today we present 21 new placebo and nocebo research papers, book chapters, comments and abstracts identified during April 2023. As usual, they are based on new PUBMED publication using the search terms „placebo“ and „nocebo“ and are hand-selected from more than 700 new publications during the preceding month.
