Arguments

cohort: A cohort_table object.
gapEra: Number of days between two continuous exposures to be considered in the same era.
conceptSet: List of concepts to be included.
ingredientConceptId: Ingredient OMOP concept that we are interested for the study.
indexDate: Name of a column that indicates the date to start the analysis.
censorDate: Name of a column that indicates the date to stop the analysis, if NULL end of individuals observation is used.
restrictIncident: Whether to include only incident prescriptions in the analysis. If FALSE all prescriptions that overlap with the study period will be included.
numberExposures: Whether to include 'number_exposures' (number of drug exposure records between indexDate and censorDate).
numberEras: Whether to include 'number_eras' (number of continuous exposure episodes between indexDate and censorDate).
daysExposed: Whether to include 'days_exposed' (number of days that the individual is in a continuous exposure episode, including allowed treatment gaps, between indexDate and censorDate; sum of the length of the different drug eras).
daysPrescribed: Whether to include 'days_prescribed' (sum of the number of days for each prescription that contribute in the analysis).
timeToExposure: Whether to include 'time_to_exposure' (number of days between indexDate and the first episode).
initialExposureDuration: Whether to include 'initial_exposure_duration' (number of prescribed days of the first drug exposure record).
initialQuantity: Whether to include 'initial_quantity' (quantity of the first drug exposure record).
cumulativeQuantity: Whether to include 'cumulative_quantity' (sum of the quantity of the different exposures considered in the analysis).
initialDailyDose: Whether to include 'initial_daily_dose_{unit}' (daily dose of the first considered prescription).
cumulativeDose: Whether to include 'cumulative_dose_{unit}' (sum of the cumulative dose of the analysed drug exposure records).
nameStyle: Character string to specify the nameStyle of the new columns.
name: Name of the new computed cohort table, if NULL a temporary table will be created.

Value

The same cohort with the added columns.
