meta analysis - where to start.


I have also posted this in random effects model - meta - analysis - where to start - Cross Validated (

I've been given a task to investigate how to carry out the meta analysis on the results from a series of studies. They all report the 'standard mortality rate' with confidence intervals. An example is below ( I am assured that the studies have been selected in line with good practice)


I have searched, read and watched numerous videos and could do with being put on the right track.

As a first step, I think that i need to assume that I should use the random-effects model and that I need to calculate an 'effect size' for each study. What method would be best to employ to obtain the effect size for each study?

I would like to understand how the calculations work before I move onto using a statistical package.

I may be asking the wrong question here so I apologise in advance.

Any help would be appreciated.
