R Metafor forest plot study labels

I have a forest plot with three subgroups and one level of each subgroup comes from the same study. Within escalc I'm using slab=paste(study) and this places the correct labels in the forest plot, but since studies are repeated they are being ended with authoryear.1, authoryear.2, authoryear.3, etc. The forest plot looks like:

Group North
Smith 2021.1
Reed 2019.1

Group Central
Smith 2021.2
Reed 2019.2

Group South
Smith 2021.3
Reed 2019.3

What I want is...

Group North
Smith 2021
Reed 2019

Group Central
Smith 2021
Reed 2019

Group South
Smith 2021
Reed 2019
Solution

  • Indeed, escalc() enforces that study labels are unique. But you can use the slab argument of the forest() function to specify the study labels and they will be used as is.
