1. A system for serial comparison of physiological data, comprising: a controller; a user interface; and a memory including instructions that, when executed by the controller, perform the steps of: receiving from a first data source a current clinical report including a first set of physiological data of a patient and computer-generated first interpretive statements; accessing, from a patient file in a patient database, a previous clinical report including a second set of physiological data of the patient and physician-edited interpretive statements; mapping the physician-edited interpretive statements into one or more codes of a structured data format and updating the previous clinical report with the one or more codes, wherein each code uniquely identifies a medical state; performing a serial comparison between the current clinical report and the updated previous clinical report and generating serial comparison interpretive statements from the serial comparison; providing to a user, via the user interface, the serial comparison interpretive statements; and receiving, via the user interface, current physician-edited interpretive statements.
