BLIND
In addition to the use of randomized controlled trials (RCTs) and triple blinding in our study, we also have a sufficient sample size, which is an important strength of the study. In our study, 160 children participated, making it the most extensive experiment ever conducted on various types of distractions for decreasing venipuncture procedure pain and fear in children. This study was designed to blind nurses, assessors, statisticians, and children from the main purpose of the study order to ensure fairness. Despite this, there are still some limitations to the generalization of our results. First, the children participating in this study were all hospitalized in a single hospital. The second limitation of the present study was that it only included school-age children. Therefore, the results may not be representative of those in other hospitals.
