Adjusted present value (APV) is a valuation method introduced in 1974 by Stewart Myers.

Effect size At the end of the study, the outcome is rated into a score, for each individual (for example on a scale of mobility and pain, in the case of an arthritis study), and then all the scores are compared between the pairs.

Effect size In other words, the correlation is the difference between the common language effect size and its complement.
