IncidencePrevalence (version 1.1.0)

estimatePointPrevalence: Estimate point prevalence

Description

Estimate point prevalence

Usage

estimatePointPrevalence(
  cdm,
  denominatorTable,
  outcomeTable,
  denominatorCohortId = NULL,
  outcomeCohortId = NULL,
  interval = "years",
  timePoint = "start",
  strata = list(),
  includeOverallStrata = TRUE
)

Value

Point prevalence estimates

Arguments

cdm

A CDM reference object

denominatorTable

A cohort table with a set of denominator cohorts (for example, created using the generateDenominatorCohortSet() function).

outcomeTable

A cohort table in the cdm reference containing a set of outcome cohorts.

denominatorCohortId

The cohort definition ids or the cohort names of the denominator cohorts of interest. If NULL all cohorts will be considered in the analysis.

outcomeCohortId

The cohort definition ids or the cohort names of the outcome cohorts of interest. If NULL all cohorts will be considered in the analysis.

interval

Time intervals over which period prevalence is estimated. Can be "weeks", "months", "quarters", or "years". ISO weeks will be used for weeks. Calendar months, quarters, or years can be used as the period. If more than one option is chosen then results will be estimated for each chosen interval.

timePoint

where to compute the point prevalence

strata

Variables added to the denominator cohort table for which to stratify estimates.

includeOverallStrata

Whether to include an overall result as well as strata specific results (when strata has been specified).

Examples

# \donttest{
cdm <- mockIncidencePrevalence(sampleSize = 1000)
cdm <- generateDenominatorCohortSet(
  cdm = cdm, name = "denominator",
  cohortDateRange = c(as.Date("2008-01-01"), as.Date("2018-01-01"))
)
estimatePointPrevalence(
  cdm = cdm,
  denominatorTable = "denominator",
  outcomeTable = "outcome",
  interval = "months"
)
# }
