ITT analysis of randomized encouragement design studies with missing data.

چکیده
In this paper, we considered a missing outcome problem in causal inferences for a randomized encouragement design study. We proposed both moment and maximum likelihood estimators for the marginal distributions of potential outcomes and the local complier average causal effect (CACE) parameter. We illustrated our methods in a randomized encouragement design study on the effectiveness of flu shots.

Background & Aim: Randomized controlled trials often suffer from two major problems, i.e., noncompliance and missing outcomes. One potential solution to this problem is using the intention-to-treat (ITT) analysis approach. Therefore, the aim of this study was to review the concept of ITT and the most important issues related to it in practice since RCT researchers utilize it as a guide in order...
متن کاملMethods for clustered encouragement design studies with noncompliance and missing data.
Encouragement design studies are particularly useful for estimating the effect of an intervention that cannot itself be randomly administered to some and not to others. They require a randomly selected group receive extra encouragement to undertake the treatment of interest, where the encouragement typically takes the form of additional information or incentives. We consider a "clustered encour...
متن کاملHandling missing data in RCTs; a review of the top medical journals
BACKGROUND Missing outcome data is a threat to the validity of treatment effect estimates in randomized controlled trials. We aimed to evaluate the extent, handling, and sensitivity analysis of missing data and intention-to-treat (ITT) analysis of randomized controlled trials (RCTs) in top tier medical journals, and compare our findings with previous reviews related to missing data and ITT in R...
متن کاملMissing outcomes in randomized trials: addressing the dilemma
A LTHOUGH RANDOMIZED TRIALS HAVE BEEN CON ducted for several decades now, some aspects of their analysis remain contentious. Two such is sues are what to do about trial participants who do not adhere to the protocol (for example, if they do not re ceive the intended treatment) and how to deal with those for whom outcome assessments are missing (for example, because they are lost to followup...
متن کاملIntention-to-treat and transparency of related practices in randomized, controlled trials of anti-infectives
BACKGROUND Intention-to-treat (ITT) analysis is commonly recommended for use, due to its benefits on external validity, in randomized, controlled trials (RCTs). No published reports describe how ITT analysis, as well as alternative approaches, are used in anti-infective RCTs. The purpose of this study is to describe the extent to which ITT analysis and alternative data approaches are used, the ...
