`exposureId`	A concept ID identifying the target drug in the exposure table. If multiple strategies for picking the exposure will be tested in the analysis, a named list of numbers can be provided instead. In the analysis, the name of the number to be used can be specified using the `exposureType` parameter in the `createCcrAnalysis` function.
`outcomeId`	A concept ID identifying the outcome in the outcome table. If multiple strategies for picking the outcome will be tested in the analysis, a named list of numbers can be provided instead. In the analysis, the name of the number to be used can be specified using the `outcomeType` parameter in the `createCcrAnalysis` function.
`nestingCohortId`	A concept ID identifying the nesting cohort in the nesting cohort table. If multiple strategies for picking the nesting cohort will be tested in the analysis, a named list of numbers can be provided instead. In the analysis, the name of the number to be used can be specified using the `nestingCohortType` parameter in the `createCcrAnalysis` function.
