A single patient is included in a single sitting RCT, a type of RCT. This enables the researcher to gather information about a person and determine whether they differ in any way from a different group of patients who didn't receive the same treatment. Most frequently, this is carried out in order to compare patients' before- and after-surgeries or procedures. https://techplanet.today/post/the-pros-and-cons-of-single-sitting-rct-in-faridabad
