The problem

In many studies, interventional or non-interventional, researchers are interested in the long-term effectiveness of treatments, in terms of overall survival. For example, in an interventional phase III clinical trial comparing two different treatments, the researchers were interested in comparing the two treatments in terms of overall survival and determining whether and which of the two treatments was associated with a higher mortality rate. For this reason, their aim was to compare the median overall survival time observed in the two compared groups.

The purpose

Indication of the most effective treatment in terms of the greatest probability of overall survival.

The solution

By using the appropriate statistical methodology (Log-rank test) and after the test of the assumptions, a comparison will be made between the two compared groups, in order to enable the user to evaluate which of the two treatments under consideration is more effective as to overall survival.

The benefit

Healthcare professionals will be able to easily, quickly and without prior statistical knowledge, evaluate the effectiveness of a treatment they are interested in, in terms of overall survival.
