ABSTRACT
The article cites several studies on randomized controlled trials (RCTs). A study conducted in 1967 by researchers Daniel Schwartz and Joseph Lellouch which stated that there are 2 kinds of RCTs, which embody radically different attitudes to evaluation of treatment. They named these trials pragmatic and explanatory and asserted that these 2 attitudes require different approaches to the design of a randomized trial.
