WebThe effect size was calculated where possible using RevMan 5.3 for Windows. The standardized mean difference (SMD) was used as a summary effect size estimator. The Cohen’s d formula was used to calculate the effect size, which is a measure of the distance between two means, measured in standard deviations (SDs). 17 WebCohen’s f is a transformation of η p 2, and is the ratio between the term- SS and the error- SS. Cohen's f p = η p 2 1 − η p 2 = S S e f f e c t S S e r r o r It can take on values between zero, when the population means are all equal, and an indefinitely large number as the means are further and further apart.
