Each method was successful in detecting intervention effect. When rank ordered, each method was consistent in identifying the participants with the largest effect. We recommend the use of the standard mean difference (SMDall) formula and we believe the use of a regression equation for calculating effect size in single subject data should be avoided UR - https://doi.org/10.1080/0144341042000301238 ER -
