 I also added (experimental!) support for additional measures (e.g., log risk ratios and risk differences) to ''[[https://wviechtb.github.io/metafor/reference/rma.glmm.html|rma.glmm()]]'' (by using log and identity links in the generalized linear mixed-effects model), but using these measures will often lead to estimation problems. For 2x2 table data, the log odds ratio (i.e., using a logit link) is still the preferred choice. I also added (experimental!) support for additional measures (e.g., log risk ratios and risk differences) to ''[[https://wviechtb.github.io/metafor/reference/rma.glmm.html|rma.glmm()]]'' (by using log and identity links in the generalized linear mixed-effects model), but using these measures will often lead to estimation problems.

-Another nice feature when computing standardized mean differences with the ''[[https://wviechtb.github.io/metafor/reference/escalc.html|escalc()]]'' function is that one can now specify d-values and t-test statistics directly. This makes it easier to assemble data for a meta-analysis with SMD values, as described [[tips:assembling_data_or|here]].+Another nice feature when computing standardized mean differences with the ''[[https://wviechtb.github.io/metafor/reference/escalc.html|escalc()]]'' function is that one can now specify d-values and t-test statistics directly.

 Aside from this, there were a few smaller improvements. The full changelog can be found [[:updates#version_38-1_2022-08-26|here]]. Aside from this, there were a few smaller improvements. The full changelog can be found [[:updates#version_38-1_2022-08-26|here]].
