how to determine what treatment is more successful statistics

A Cohen’s d greater than zero indicates the degree to which one treatment is more efficacious than the other. 3 A conventional rule is to consider a Cohen’s d of 0.2 as small, 0.5 as medium, and 0.8 as large. 4 A Cohen’s d score is frequently accompanied by a confidence interval (CI) so that the reliability of the comparison can be assessed.

Cohen suggested that d = 0.2 be considered a 'small' effect size, 0.5 represents a 'medium' effect size and 0.8 a 'large' effect size. This means that if the difference between two groups' means is less than 0.2 standard deviations, the difference is negligible, even if it is statistically significant.
