Analytic conventions describe how data on donors, organs, transplants, and transplant operations were tabulated for the Program-Specific and Organ Procurement Organization reports.

• A good first step is our slide show titled "The SRTR Program-Specific Reporting Tools: Key Points." These slides describe the content of the Program-Specific Reports, as well as the data flow process and the role of the SRTR. There are also slides explaining how survival is calculated and the concept of risk adjustment, including some simple examples to demonstrate these concepts.
• Similarly, a good place to begin understanding the OPO-Specific Reports is our slide show titled "A Guide to the SRTR OPO Reports." These slides describe the content of the OPO-Specific Reports, including counts of donors, characteristics of donors, organs recovered and organs transplanted by Donation Service Area. Addtionally, there is a description of the process for computing organ donation conversion rates.
• More detail that may help you understand and assess differneces in outcomes can be found in the 2007 SRTR Report on the State of Transplantation: SRTR Program-Specific Reports on Outcomes. This article presents a basic explanation of the tools available for evaluating differences in outcomes and how their interpretation should be considered in the context of reading the SRTR Program-Specific Reports.
• A broad overview of the post-transplant outcomes (graft and patient survival) included in these reports is detailed in an article from the 2005 SRTR Report on the State of Transplantation. SRTR Center-Specific Reporting Tools: Posttransplant Outcomes. This article provides good background on the statistical concepts and methodologies used in these reports.
• Additional information about the Program-Specifc Reports can be found in the Frequently Asked Questions (FAQs).
• Further details about the reports are contained in the Technical Methods for each report:
