Standardized mean difference (d) is commonly used to express the size of an intervention effect in controlled experiments. Pearson's correlation coefficient (r) can be used to measure the strength and direction of a linear relationship between two variables in meta-analyses. The odds ratio (OR) is also used in meta-analyses, especially in studies dealing with binary outcomes, to compare the odds of an event occurring in one group to the odds of it occurring in another group.
