However, for a fixed number of participants, it is statistically most efficient to divide them into equal-sized groups. A final solution to the problem of placebo effects is to leave out the control condition completely and compare any new treatment with the best available alternative treatment. The tailored participant-matching process reduces the risk of participant variables (individual differences) from affecting results between conditions.
