The pancreas has many functions related to digestion and the regulation of blood sugar levels. Pancreatitis is a disease caused by inflammation of the pancreas..
causes as censoring events, the concept of relative survival was developed by comparing the observed survival probability of a group of cancer patients with the survival of a âsimilarâ cancer-free group. Relative survival is defined as the ratio of the observed survival (all cause survival) of a cohort of cancer patients to the expected survival of a comparable set of cancer free individuals.
The relative risk is normally reported as calculated for the mean of the sample values of the explanatory variables. Comparison to the odds ratio Relative risk is different from the odds ratio, although it asymptotically approaches it for small probabilities. In the example of association of smoking to lung cancer considered above, if a is substantially smaller than b, then a/(a + b) â a/b.
