|---|---|---|---|---|---|
| Pattern Type | Documented Subtypes | Subtypes Identified (%) | Subtypes Identified (%) | Subtypes Identified (%) | Subtypes Identified (%) |

a
This considers the number of subtypes identified within cases and controls respectively, over the total number of previously documented subtypes. Note that the denominator is includes documented subtypes identified within this sample.
b
Includes all subtypes identified between both sets of control groups.
