# mechanism must be independent of the survival mechanism. There are generally three reasons why censoring might occur: • A subject does not experience the event before the study ends • A person is lost to follow-up during the study period • A person withdraws from the study These are all examples of right-censoring.

Let's say you're interested in 5-year disease-free survival (assuming that is clinically or biologically relevant); then you just focus on that part of the curve, and the follow-up is finished after the first 5 years (although you have longer follow-up data available; you don't use it). Kaplan-Meier Procedure (Survival Analysis) in SPSS - YouTube. This video provides two demonstrations of survival analysis using the KM method in SPSS. A copy of the data can be downloaded here (https://drive.google.com/ How to perform survival analysis in spss 4 and 5 year succession). In addition, the survival time should be clearly defined, whether measured in days, weeks, months, years or another time-based measurement.

In survival analysis the survival probabilities are usually reported at certain time points on the curve (e.g. 1 year and 5 year survival); otherwise the median survival time (the time at which 50% of the subjects have reached the event) can be reported.

To calculate a rate to survive women ages 25–29 into the next 5-year age cohort (30–34), use the following numbers from the L x column in Table 7-1, as shown in the following example. In survival analysis the survival probabilities are usually reported at certain time points on the curve (e.g. 1 year and 5 year survival); otherwise the median survival time (the time at which 50% of the subjects have reached the event) can be reported.

he saw concerning Israel two years before the earthquake, when Uzziah was king of When I used spss to analyze KM survival, it gave me mean and median survivals with 95 % confidence interval. However, I need 1-, 3- and 5- year survival too. It's difficult to figure out using the curves. If the length of the experiment was 5 years, at the end of the 5-year period, all participants would either be "censored" or "dead". Therefore, the two states should not only be mutually exclusive, but also collectively exhaustive (i.e., at least one of these states – censored or event – must occur).

### The Kaplan-Meier method, unlike some other approaches to survival analysis (e.g., the actuarial approach), requires the survival time to be recorded precisely (i.e., exactly when the event or censorship occurred) rather than simply recording whether the event occurred within some predefined interval (e.g., only recording when a death or censorship occurred sometime within a 1, 2, 3, 4 and 5 year follow-up). In addition, the survival …

### I have a database with patients and did survival analysis in SPSS. SPSS gave me the mean and median survivals with 95% confidence intervals. However, I also want the 1-,3-, and 5-year survival times with 95% confidence interval. I can of course estimate it from the curve but I was wondering if there is a more precise way?
