Statistic.numberOfEvents
Element IdStatistic.numberOfEvents
Definition

The number of events associated with the statistic, where the unit of analysis is different from numberAffected, sampleSize.knownDataCount and sampleSize.numberOfParticipants.

Cardinality0..1
TypeunsignedInt
Summarytrue
Comments

When the number of events is the statistic, use Statistic.quantity and set Statistic.type.coding.code=C25463 and Statistic.type.coding.display=Count. When the statistic is an Event Rate (where individual participants may have 2 or more events), use Statistic.numberOfEvents to record the total number of events rather than the number of participants with events.

Statistic.numberAffected
Element IdStatistic.numberAffected
Definition

The number of participants affected where the unit of analysis is the same as sampleSize.knownDataCount and sampleSize.numberOfParticipants.

Comments

When the number affected is the statistic, use Statistic.quantity and set Statistic.type.coding.code=C25463 and Statistic.type.coding.display=Count. When the statistic is a Proportion, use Statistic.numberAffected and enter an integer as the value. When the statistic is an Event Rate (where individual participants may have 2 or more events), use Statistic.numberAffected to record the number of participants with events rather than the total number of events.
