Hi Gloria, This is YyvTao. We were in contact during the summer break regarding a meta analysis project. Unfortunately, I was not able to continue that work, due to car accidence, later family death and sickness of family member. Sorry about that!
Anyhow, I have great interest in your current project. I read through the paper already, and it would like to implement the R code if you send the data to me. I need a week though. If it does not meet your expectation, I will not charge anything. Looking forward to hearing from you!
