Forest plots: trying to see the wood and the trees

I am writing a systematic review about antidepressants. For this I need a “forest plot”. Found a nice and comprehensive article in the BMJ.
In short this what a “forest plot” is:
Forest plots show the information from the individual studies that went into the meta-analysis at a glance
They show the amount of variation between the studies and an estimate of the overall result.
And here is link with a spreadsheet to make a forest plot in excel:

  1. Dear Dr. Shock,

    My name is Ioannis Kareklas and I am a PhD student at the University of Connecticut. I am working on a meta-analysis of racial similarity effects in advertising and would love to get a copy of your spreadsheet to make forest plots in excel

    Unfortunately, the link posted on this website is not working.
    I would greatly appreciate it if you send me a working link or e-mail me the file @ ioanniskareklas@gmail.com.

    Thank you.
