An IV for the RCT: using instrumental variables to adjust for treatment contamination in randomised controlled trials
Sussman, JB, Hayward, RA. An IV for the RCT: using instrumental variables to adjust for treatment contamination in randomised controlled trials. BMJ 2010;340:c2073.
Our own Dr. Sussman writes:
"In this article, we describe a simple yet rarely used analytical technique, the "contamination adjusted intention to treat analysis," which complements the intention to treat approach by producing a better estimate of the benefits and harms of receiving a treatment. This method uses the statistical technique of instrumental variable analysis to address contamination."
I'll find a link and post it here...

This is worth a read no matter what.
The 2010 Schedule
Here are our planned Journal Club dates. When a Journal Club date precedes a scheduled Brownbag Speaker, I've noted it:
- September 15 (Tom Fitzgerald)
- September 29
- October 6 (Jake Seagull)
- October 20 (Caren Stallburg)
- November 3 (Brent Stansfield)
- November 17
- December 1 (Pamela Andreatta)
- December 15 (Ameed Raoof)
We like to have Journal Club articles relate to the topics of the following weeks' Brownbag Speaker. Dates with no speaker are fair game!
