5.2 Layout types

The meta::forest function also has two Layouts preinstalled which we can use. Those layouts can be accessed with the layout parameter.

  • “RevMan5”. This layout is used for Cochrane reviews and generated by Review Manager 5.
  • “JAMA”. This layout gives you a forest plot according to the guidelines of the Journal of the American Medical Association as output (see details here).

The RevMan layout looks like this:

forest(m.hksj.raw,
       layout = "RevMan5",
       digits.sd = 2)

The JAMA layout looks like this:

forest(m.hksj.raw,
       layout = "JAMA",
       text.predict = "95% PI",
       col.predict = "black",
       colgap.forest.left = unit(15,"mm"))
