Example

library(SelfControlledCohort)

connectionDetails <- createConnectionDetails(dbms = "postgresql",
                                             user = "joe",
                                             password = "secret",
                                             server = "myserver")
                                             
sccResults <- runSelfControlledCohort(connectionDetails,
                                     cdmDatabaseSchema = "cdm_data",
                                     exposureIds = c(767410, 1314924, 907879),
                                     outcomeIds = 444382,
                                     outcomeTable = "condition_era")
