Sažetak
The pitfall of performing statistical analysis regarding retrospective survival analysis is that the investigators should considered an issue of competing risks. Competing risk appears when one of the events can prevent or modify the chance of occurrence of the event of interest. The researchers using the standard method of survival analysis (Cox regression) for their time-to-event analysis, actually use suboptimal method due to the fact that it wrongly presumes random and noninformative censoring (independent of the event of interest) However, censoring due to death is informative as it precludes the event of interest from occurring. As a result, we can expect falsely higher estimates of the event of interest in the group with less censoring, in this case the liraglutide group. The method for competing risk analysis, such as the method developed by Fine and Gray takes into consideration informative censoring together with all the observed events. Consequently, it interprets the effect of interest depending on the magnitude of the risk of other competing events.
