Eloonjäämisaste

Eloonjäämisaste, meaning survival rate in Finnish, is a statistical measure indicating the proportion of individuals within a defined group who survive a specific event or over a particular time period. It is commonly used in various fields, including medicine, ecology, and demography, to assess outcomes and trends.

In medicine, eloonjäämisaste is crucial for evaluating the effectiveness of treatments, particularly for diseases like cancer. For instance, a 5-year survival rate for a specific cancer indicates the percentage of patients diagnosed with that cancer who are still alive five years after their diagnosis. This metric helps researchers and clinicians understand prognosis and compare different therapeutic approaches.

In ecology, eloonjäämisaste is applied to populations of plants or animals. It can refer to the survival rate of seedlings in a new environment, the survival of young animals through their first year, or the overall survival of a population facing environmental pressures such as predation, disease, or climate change. This data is vital for conservation efforts and understanding population dynamics.

Demographers use eloonjäämisaste to analyze mortality patterns across different age groups and populations. Life tables, for example, present eloonjäämisaste at various ages, providing insights into life expectancy and the impact of public health initiatives. Overall, eloonjäämisaste serves as a key indicator for assessing survival and health outcomes in diverse contexts.
