)
cohort |
A cohort table in a cdm reference. |
ageRange |
A list of vectors specifying minimum and maximum age. |

name |

Whether to perform a soft validation of consistency. If set to FALSE four additional checks will be performed: 1) a check that cohort end date is not before cohort start date, 2) a check that there are no missing values in required columns, 3) a check that cohort duration is all within observation period, and 4) that there are no overlapping cohort entries |
