You don't have to do anything as long as you can reasonably believe
that the probability of missingnes is independent of dprt (whatever
that may be). Notice that this is something you can see in your data.
In many situations, that is the safest solution. If you need a
reference, you can cite: Allison, Paul D.  (2001). Missing data.
Thousand Oaks: Sage.

Multiple imputation would be my second choice. You would have to
include all variables in your model (including your dependent
variable!!) in imputation model.

But all this depends on the details of the problem.
