Figure 1: Graphical depiction of the concept of event and censoring. Each line represents a single patient and the blue-shaded area is the time during which the study runs. Patients whose lines terminate in a circle experienced the event, while others have not. As shown, few may experience the event at the end of the observation period, but others may not. In addition, entries into the study are staggered. Some patients do not complete the observation period but do not experience the event either (e.g., lost to follow-up). In this case, all patients except the two who experience the event within the study duration will be censored
