Greetings!

I am working on a meta-analysis validating a tool's diagnostic accuracy. One of the studies to be pooled holds zero value in one of the cells. I read that adding 0.5 as a continuity correction would be best, and I made it accordingly to the cell specified. However, the Stata software can not process the analysis, reporting that it is a must to use integers. There also some other recommendations to add 0.5 for all the cells for the sake of compensation. Which one is correct?

Is there anyone who can help me in fixing it in the Stata using the commands?
