True,the risk difference is an example of an absolute measure to compare the extent of disease between groups.
When weighing trade-offs between the expected benefits and the likely dangers of an action, absolute measurements like the risk difference are very helpful. Similar to the risk ratio, the risk difference is intrinsically restricted, which may make it challenging to generalise findings to other patient populations and environments. Absolute risk is the difference between risks. focuses on the number of cases that might potentially be avoided by removing the risk factor and offers a measure of the risk factor's influence on public health.
