cohort_table objects constructor.

cohort_table objects constructor.

Usage

newCohortTable(
  table,
  cohortSetRef = attr(table, "cohort_set"),
  cohortAttritionRef = attr(table, "cohort_attrition"),
  cohortCodelistRef = attr(table, "cohort_codelist"),
  .softValidation = FALSE
)

Arguments

table

cdm_table object with at least: cohort_definition_id, subject_id, cohort_start_date, cohort_end_date.

cohortSetRef

Table with at least: cohort_definition_id, cohort_name

cohortAttritionRef

Table with at least: cohort_definition_id, number_subjects, number_records, reason_id, reason, excluded_subjects, excluded_records.

cohortCodelistRef

Table with at least: cohort_definition_id, codelist_name, and concept_id.

.softValidation

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

Value

A cohort_table object
