April 21 meeting options

Dear all,

I hope that some of you will be able to join us next week for the
stats and epidemiology journal club on Wednesday April 21. The
meeting will be held at 1pm in the 2nd floor meeting room in the
Rosemary Rue Building.

I have attached three possible papers for discussion. If you are
interested in coming, please send me back your vote for which paper
you'd like to discuss. The options are:

1. Bias in identifying and recruiting participants in cluster
randomised trials: what can be done?
Sandra Eldridge and colleagues,
BMJ. 2009 Oct 9;339:b4006.
A discussion of how to design cluster randomized trials to minimize
selection bias

2. More Than Numbers: The Power of Graphs in Meta-Analysis. Leon Bax
and colleagues, Am J Epidemiol. 2009 Jan 15;169(2):249-55
What graphs should we use to report the results from a meta analysis?
A comparison for some of the popular options and limitations in each.

3. Power for studies with random group sizes. Walter T. Ambrosius,
Stat Med. 2010 Mar 11.
How to appropriately conduct a power calculation for observational studies

Let me know by next Monday and I will circulate the winning paper! Just email me at nada.khan@dphpc.ox.ac.uk.
