According to many online reviews, an easy way to do Forest Plots (Forrest Plots) is supposedly to use the free RevMan software. RevMan (currently RevMan5) can be downloaded here. RevMan is a software geared towards medical statistical analysis.
RevMan is said to be the easiest method since at least it has a graphical user inferface (GUI). For total beginners, before even doing the Forest Plot, we need to learn how to enter the data into RevMan.
Overall, I think RevMan should be one of the easiest ways to do Forest Plots or meta-analysis. Furtheremore, the software is completely free. However, there is still a significant learning curve.
