The two are unrelated but you can infer a few things ..
If the STODA is established by inclino survey, it will give you a straightout obstacle clear gradient surface. However, be wary, many are determined by calculation from, say, Type A data, and will only address a specific distance out from the runway head.
If you are looking at a turn, all bets are off as the STODA data only looks at a straight ahead flight path, unless otherwise specified.
I doubt that you will find anything in the rule books about using STODA data .. it is presumed that the basic definition provides the information needed for operations.
