Intention-to-treat analysis: Are we managing dropouts and missing data properly in research on orthodontic treatment? A systematic review

Intention-to-treat (ITT) analysis is an approach to managing dropouts and missing data in randomized controlled trials (RCTs). In this study, we systematically reviewed orthodontic RCTs to assess the frequency that an ITT analysis was carried out, to compare the number of trials that reported using ITT analyses with those that had truly used it, and to evaluate how dropouts and missing data were managed.
