+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ HANDLING MISSING OUTCOME DATA IN RANDOMISED TRIALS MRC BIOSTATISTICS UNIT, CAMBRIDGE 14-15 March 2012 Lecturers: Ian White, Simon Bond, Shaun Seaman, Adrian Mander, James Wason. Please see http://www.mrc-bsu.cam.ac.uk/HTMRmiss/ for more details and online registration form. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ COURSE AIMS * Review some popular ways to analyse trials with missing data, focussing on the assumptions underlying them * Discuss what assumptions may be plausible and how one should decide this in particular trials * Describe the theory for mixed models analysis of incomplete data, how they should be implemented, and what are the pitfalls * Demonstrate how to analyse data using mixed models and multiple imputation in Stata, R and SAS * Discuss the advantages and disadvantages of the two methods * Discuss the different issues involved in handling missing baselines The workshop will provide practising statisticians with the necessary practical skills to handle missing data in their analyses, and in particular to move beyond the use of complete-case analysis and last observation carried forward analysis. We will focus on trials with quantitative outcomes, and also consider binary outcomes but not time-to-event outcomes. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ TARGET AUDIENCE * Statisticians who analyse clinical trials with missing outcome data. * Participants are asked to bring their own laptops with their preferred statistical software (R, SAS or Stata). ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ COSTS * Student £100 * Public sector £200 * Commercial £400 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ You may leave the list at any time by sending the command SIGNOFF allstat to [log in to unmask], leaving the subject line blank.
