medical system, can be reduced; or, at a minimum, the rate of cost increase can be minimized. In an illustrative embodiment, dynamic analytical framework 1500 can be manipulated to access or receive information from only selected ones of sources of information 1502 , or to access or receive only selected data types from sources of information 1502 . For example, a user can specify that dynamic analytical framework 1500 should not access or receive data from a particular source of information. On the other hand, a user can also specify that dynamic analytical framework 1500 should again access or receive that particular source of information, or should access or receive another source of information. This designation can be made contingent upon some action trigger. For example, should dynamic analytical framework 1500 receive information from a first source of information, dynamic analytical framework 1500 can then automatically begin or discontinue receiving or accessing information from a second source of information. However, the trigger can be any trigger or event. In a specific example, some medical professionals do not trust, or have lower trust of, patient-reported data. Thus, a medical professional can instruct dynamic analytical framework 1500 to perform an analysis and/or inference without reference to patient-reported data in sources of information 1502 . However, to see how the outcome changes with patient-reported data, the medical professional can re-run the analysis and/or inference with the patient-reported data. Continuing this example, the medical professional designates a trigger. The trigger is that, should a
