Abstract: A dynamic user interface is configured to generate two types of information that may be generated by sophisticated computer systems such as expert systems and/or artificial intelligence. These types and include a “what if” prediction that illustrates probable outcomes from alternative actions, and a “similarity” analysis which shows a user how adjustments to input data may affect the resulting predictions. The “what if” prediction provides users guidance as to what actions may be most beneficial. The “similarity” analysis helps the users understand consequences of medical decisions.
