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...
This study deals with the question of how to model health effects after the cessation of a randomized controlled trial (RCT). By using clinical trial data on severe congestive heart failure patients, we illustrate how survival beyond the cessation of an RCT can be predicted based on parametric survival models. In the analysis, we compare predicted survival and the resulting incremental cost-eff...

In this section of the series on orthodontic research we intend to give a brief outline of how to carry out a randomized controlled trial (RCT). The RCT is one of the most simple and powerful research tools in which people are allocated at random to receive one of several clinical interventions. We hope that this will not only provide information to anyone who is aiming to carry out research of...
Endovascular coiling has become the primary treatment modality for the treatment of intracranial ruptured aneurysms in many centers. A multicenter randomized controlled trial (RCT), ISAT study, has demonstrated that endovascular coiling of ruptured intracranial aneurysms has benefits over surgical clipping in those patients suitable for either treatment. Because RCT comparing conservative manag...
