<unk>  is a part of survival analysis. It is the percentage of people in a study or treatment group still alive for a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions.<unk>  can be used as yardstick for the assessment of standards of therapy. The survival period is usually reckoned from date of diagnosis or start of treatment.<unk> s are important for prognosis, but because the rate is based on the population as a whole, an individual prognosis may be different depending on newer treatments since the last statistical analysis as well as the overall general health of the patient. There are various types of<unk> s (discussed below). They often serve as endpoints of clinical trials and should not be confused with mortality rates, a population metric.
