14.13.0 Statistic

Clinical Decision Support

Work Group

Maturity Level: 0

Standards Status: Trial Use

This type is still undergoing development and review by the appropriate Workgroups. At this time, is considered only as a draft design not suitable for production implementation

The Statistic data type represents single datum (quantitative value), computed from a sample, and its attributes.

Note: the Statistic structure allows modifier extensions.
