ABSTRACT
Interim data monitoring is an important part in the life of a clinical trial. Interim data monitoring has (1) an ethical attractiveness as it can result in fewer patients being exposed to potentially harmful and inefficacious interventions, (2) economical advantages in that research questions may be able to be answered sooner, and (3) a public health impact since trial results may be communicated to the medical community faster. Thus, appropriate thought should be given to how a trial should be monitored.
