In a controlled, randomized crossover designs, such imbalances are implausible (unless covariates were to change systematically during the study). Second, optimal crossover designs are statistically efficient , and so require fewer subjects than do non-crossover designs (even other repeated measures designs).
All participated in two randomized crossover trials separated by at least seven days. The four-hour trials — which included meals and measurement-taking — were identical except that one ...
Randomized, controlled, crossover experiments are especially important in health care. In a randomized clinical trial , the subjects are randomly assigned treatments. When such a trial is a repeated measures design, the subjects are randomly assigned to a sequence of treatments.
All the included studies were either randomized crossover studies or randomized controlled trials lasting at least 4 weeks. The studies included healthy adults and examined how time-restricted ...
An N of 1 trial (N=1) is a multiple crossover clinical trial, conducted in a single patient. [1] A trial in which random allocation is used to determine the order in which an experimental and a control intervention are given to a single patient is an N of 1 randomized controlled trial.
The main study cited was of just 59 men to see if their oral microbiomes changed after using either Cool Mint Listerine or a placebo mouthwash ... a randomised, placebo-controlled, crossover trial."

A randomized controlled trial (or randomized control trial; [2] RCT) is a form of scientific experiment used to control factors not under direct experimental control.
