Summarise the number of people in observation during a specific interval of time

Usage

summariseInObservation(
  observationPeriod,
  interval = "overall",
  output = "record",
  ageGroup = NULL,
  sex = FALSE,
  dateRange = NULL
)

observationPeriod: An observation_period omop table. It must be part of a cdm_reference object.
interval: Time interval to stratify by. It can either be "years", "quarters", "months" or "overall".
output: Output format. It can be either the number of records ("record") that are in observation in the specific interval of time, the number of person-days ("person-days"), the number of subjects ("person"), the number of females ("sex") or the median age of population in observation ("age").
ageGroup: A list of age groups to stratify the results by. Each element represents a specific age range. You can give them specific names, e.g. ageGroup = list(children = c(0, 17), adult = c(18, Inf)).
sex: Logical; whether to stratify results by sex (TRUE) or not (FALSE).
dateRange: A vector of two dates defining the desired study period. Only the start_date column of the OMOP table is checked to ensure it falls within this range. If dateRange is NULL, no restriction is applied.

A summarised_result object with the results.
