WebbEach study has its own standardised mean difference (SMD), which is calculated by taking the difference in the group means and dividing by the standard deviation of the groups. There are also associated 95% confidence intervals. The most important number to look at here is the pooled SMD, which is in bold underneath the individual study SMDs. WebbThe standardized mean-difference effect size (d) is designed for contrasting two groups on a continuous dependent variable. It can be computed from means and standard deviations, a t-test, and a one-way ANOVA. Methods have also be developed for estimating dbased on a dichotomous dependent variable.

WebbA transformation of a SMD to a (log) odds ratio is available, based on the assumption that an underlying continuous variable has a logistic distribution with equal standard deviation in the two intervention groups(Furukawa 1999, Chinn 2000). The assumption is unlikely to hold exactly and the results must be regarded as an approximation. Webb28 okt. 2024 · However, in some studies outcome variables are measured in difference scales (e.g., cm and inch, or kg and lb). So, direct comparison of means in two different units, using the raw mean difference, is not meaningful. Instead, the raw mean difference is divided by the standard deviation (pooled or not) to find the standardised mean …

Webb4 For example, a standardized difference of 0.2 indicates that there is 15% of non-overlap in the two distributions (U1), that 54% of control group observations with values greater than 54% of treatment group observations (U2), and that the mean of the treated group is at the 58 th percentile of the control group.
