 However, for the purpose of Mortality, Morbidity, or other uses we need to identify only one parent for each of the categories. We call the different uses - Mortality, Morbidity, etc. - '''linearizations''', and their main characteristic is that each category in a linearization has exactly one parent. This is a very important feature for statistical purposes, to make sure that a disease is counted only once when compiling a statistics.

 It is also possible to '''skip several levels in a linearization'''. This can be done by selecting one of the ancestors of the parents from the Foundation layer.

 === iCat Linearization ===
 == Overview ==
-* Linearization in iCat allows the same entity to be a child of two parents, but only counted as a child of one parent for particular purposes.
-* For example, Bacterial Pneumonia is both an infection and a respiratory disease. The same code can be used to describe this disease, but have different parents depending on whether the same code could be used for a particular disease, but have different parents depending on if it is entered for the purpose of morbidity or for mortality.
+iCAT allows the browsing and editing of the '''ICD-11 Foundation Layer'''. In the Foundation Layer, one category can have '''multiple parents'''. For example, Bacterial Pneumonia is both an infection and a respiratory disease, and therefore can have parents from both of this chapters.
-* This directly affects the way in which statistics are aggregated under particular categories. In some cases (say a classification of morbidity) we might want to classify Bacterial Pneumonia as a disease. In that case, all incidents of Bacterial Pneumonia add one count to the tally of all diseases. If we were more interested in infections, then each case of Bacterial Pneumonia could be counted as an infection.
