All, we've prepared a manuscript detailing the strategy and providing examples and code in two major platforms (R and Stata). If you are interested to see it, please send me an email.

Most books on meta-analysis skim around this issue, since one essentially has to use matrix algebra notation to write down the required equations. However, if I remember correctly, the chapter by Raudenbush in the Handbook should have them.<br />

A plot of what you have in mind can be found in my paper on the metafor package (<a href="http://www.jstatsoft.org/v36/i03/" target="_blank">http://www.jstatsoft.org/v36/i03/</a>). In particular, see Figure 2. It shows the estimated/predicted relative risk…

In particular, see Figure 2. It shows the estimated/predicted relative risk as a function of absolute latitude for the BCG vaccine data. The corresponding 95% confidence interval bounds are also added to the plot.<br />

I think figures like this are quite underused in meta-analyses. Many people would end up dichotomizing the moderator (i.e., close to equator, far from equator) and fit separate random-effects models within each level.
