Hello, I am currently using Stata/SE14.1 and I simply tried the following codes

metan ln_HR ln_LCI ln_UCI, random hr label(namevar= author, yearvar= yearofpublication) forestplot( texts(100) title(Dabigatran vs Warf on stroke/SE) favours(Favor Dabigatran#Favor Warfarin))

But I got the error message: option hr not allowed r(198);

Is there anyway to fix this problem?
