The purpose of this page is to capture information about complex comparisons that is not easily conveyed on the treatment regimen pages. Many complex multipart RCTs are of the "Y-shaped" format "A followed by B1 versus B2" or "A1 versus A2 followed by B" and this can be captured on the treatment regimen pages. This page will convey information on more complicated designs, such as "A followed by B versus B followed by A" or "A followed by B versus C followed by D".
