Create Self-Controlled Risk Interval (SCRI) era data

createScriIntervalData(
  studyPopulation,
  sccsData,
  eraCovariateSettings,
  controlIntervalSettings
)

Arguments

studyPopulation

An object created using the createStudyPopulation() function.

sccsData

An object of type SccsData as created using the getDbSccsData function.

eraCovariateSettings

Either an object of type EraCovariateSettings as created using the createEraCovariateSettings() function, or a list of such objects.

controlIntervalSettings

An object of type ControlIntervalSettings as created using the createControlIntervalSettings() function.

Value

An object of type SccsIntervalData.

Details

This function creates interval data according to the elf-Controlled Risk Interval (SCRI) design. Unlike the generic SCCS design, where all patient time is used to establish a background rate, in the SCRI design a specific control interval (relative to the exposure) needs to be defined. The final model will only include time that is either part of the risk interval (defined using the eraCovariateSettings argument, or the control interval (defined using controlIntervalSettings).
