Ordinary least squares regression methods fall short because the time to event is typically not normally distributed, and the model cannot handle censoring, very common in survival data, without modification. = 6.9%. For an additional 5 units increase in BMI, the hazard decreases by (1 – 0.931. 5)*100 = 30% For age group, the reference category is < 60.

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 time should be clearly defined, whether this is measured in 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? You can ask SPSS to display the life tables as output for Kaplan-Meier procedure.

The five-year survival rate is a type of survival rate for estimating the prognosis of a particular disease, normally calculated from the point of diagnosis. Lead time bias from earlier diagnosis can affect interpretation of the five-year survival rate. Obtaining a Kaplan-Meier Survival Analysis. This feature requires the Advanced Statistics option.

So if you are using SPSS in the year 2020, it will assume that the century range is 1951 to 2050; but if you open SPSS a year later, SPSS will assume that the century range is 1952 to 2051. The survival of 87 subjects at the end of the first year would give a one-year survival probability estimate of 87/100=0.87; the survival of 76 subjects at the end of the second year would yield a two-year estimate of 76/100=0.76; and so forth.
