A Study on survival analysis

Survival times are used to compare the treatments. Survival data, a special type of data, have to be analyzed with special methods. when survival times are analyzed without the use of special techniques, or when the underlying assumptions were not taken into an account, then faulty interpretation may result. Readers should know these pit-falls and be able to judge for themselves whether the chosen analytical method is correct. The present article is based on textbooks of statistics, a selective review of the literature, and the authors own experience. This article suggest the guidelines for the presentation of survival analyses in medical journals. These would be the complement on statistical guidelines recommended by several medical journals.
