Like so many of the others on this forum, I've had terrible sinus headaches after having a root canal done 3 weeks ago. It started as soon as the Novocaine wore off. It was almost unbearable for the first 2 days. It began around my right eye and nose (the root canal was in my upper right side).
Survival analysis is generally defined as a set of methods for analyzing data where the outcome variable. is the time until the occurrence of an event of interest. The event can be death, occurrence of a disease, marriage, divorce, etc. The time to event or survival time can be measured in days, weeks, years, etc.
A survival curve is a statistical picture of the survival experience of some group of patients in the form of a graph showing the precentage surviving versus time.A survival curve cannot be summed up with a single number such as the median survival or the five year survival, despite all too frequent attempts to do so.ou can't tell that from the median or 5 year survival or from any other single point. It's the shape of the survival curve that tells this story. Now, of course, this is merely a hypothetical example-but some real world survival curves really do look a lot like my example.
