This gives a true value if the test value has not increased from the previously available value, that is, if the test value is the same or has decreased.

For example, given the following case fragment:

           01 Jun 03    20 Jun 03    30 Jun 03    15 Oct 03    02 Nov 03
HDL           2.0          2.1          2.2          2.5          2.5
LDL                        6.2          5.0                       4.9
Trig          3.6                                    3.6
LipidDrug     N                         Y            Y
