WebA matched pairs design is a special case of the randomized block design. It is used when the experiment has only two treatment conditions, allowing participants to be grouped into pairs based on some blocking variable. Within each pair, participants then are randomly assigned to different treatments. Webing at random. If one patient in a patient pair is missing data for an endpoint, then we simply proceed to compare the pair at the next level.
