NIH Websites Are Changing

Beginning in late July, NIH will start introducing a new website experience designed to make it easier to find health information, research, funding opportunities, and other resources. During the transition, you may notice changes to navigation, page layouts, and where some information is located.

Use the Tool

This tool provides a range of possible outcomes for infants born extremely preterm. The outcomes are based on data from infants born at specific U.S. hospitals between 2006 and 2012. “Hospital range” in the tool results represent outcomes for 80% of hospitals included in this study (10th to 90th percentiles). Please note that the tool describes outcomes for groups of infants with similar characteristics. It does not predict outcomes for any individual infant. Visit About the Data to learn more.

Please enter information available at the time of birth to use the tool.
