Have you ever tried to implement multiple imputation with several incomplete variables? How do you know whether MI will be valid for your data? We have just published an easy to use algorithm using modifications to DAGs (now they're colourful) to aid decision making with MI

Great end-of-year news (yes, I'm braggingâbut I can't hold back my excitement over this team effort): Our paper on acetaminophen safety was one of the most popular in *JAMA* this year!
