Hi, is there a way to display math symbols like "greater than or equal to" as value labels and have them printed as titles for subgroups in a forest plot (figure below)?

Array

My dataset looks like this
First author and year Values Population
..... ..... PLHIV (median CD4 <350)
..... ..... PLHIV (median CD4 "greater than or equal to" 350)
..... ..... .....
Thanks!
