1. A method for comparing two groups of records comprising: receiving a medical code; searching a database stored on a data storage device to obtain a first group of records associated with individuals having the medical code, wherein each record of the first group of records includes a plurality of test codes, and wherein each of the test codes comprises one or more lab values; searching the database to obtain a second group of records associated with a control population, wherein each record of the second group of records includes the plurality of test codes; and evaluating a first percentile lab value for each test code of the first group of records representative of each of the one or more lab values of each test code; evaluating a second percentile lab value for each test code of the second group of records representative of each of the one or more lab values of each test code, wherein each test code for which a second percentile lab value is evaluated is also a test code in the first group of records; determining a relevancy of each test code to the medical code based on the first percentile lab value for each test code and the second percentile lab value for each test code; comparing a first percentile lab value representing a particular test code in the first group of records and a second percentile lab value representing the same particular test code in the second group of records; and generating an output comprising a distribution graph on a shared scale from the first and second group of records, wherein the output displays the relevancy of each test code to the medical code.
