Question Posted 08/23/17:
Hi there,

I was wondering if you could help me with drop-out effects. I cannot find the data that describes drop-out due to leaving the study or death. I have found the adverse events files when death is recorded, but I suspect this is greatly underestimating the numbers of drop outs from the study. I suspect these missing data are causing fat tails in my MLM residuals and so I would like to account for them.
Your help would be hugely appreciated.

Warm regards,
Jack Rivers-Auty

Have you also checked the Early Discontinuation and Withdrawal file (under the Enrollment section of the list of files)?
