The grid shows all tests that have been executed on the patient.  You may want to filter these and only see specific results, such as those executed by a certain tester, on a certain date or with a certain stimulus, or only results with a certain hearing aid.


The most straightforward way to do this is to double-click on the field of your choice.


For instance, double-clicking on this field...

... filters the grid to results obtained with this aid only...


The filter can be switched off by double-clicking once again on the same field.


Alternatively, you may want to refine the filter, for instance, to see all aided results, irrespective of the exact type of hearing aid or implant.  This can be achieved by clicking on the small pin in the column header...

The drop-down window now allows you to define the filter exactly as you like it.
