R Documentation

Get Portfolio Configuration

Description

Get Portfolio configuration from a dataframe aggregated on patient level with max_ae and max_visit. Will filter studies with only a few sites and patients and will anonymize IDs. Portfolio configuration can be used by sim_test_data_portfolio to generate data for an artificial portfolio.

Usage

get_config(
  df_site,
  min_pat_per_study = 100,
  min_sites_per_study = 10,
  anonymize = TRUE,
  pad_width = 4
)

Arguments

`df_site`	dataframe aggregated on patient level with max_ae and max_visit
`min_pat_per_study`	minimum number of patients per study, Default: 100
`min_sites_per_study`	minimum number of sites per study, Default: 10
`anonymize`	logical, Default: TRUE
`pad_width`	padding width for newly created IDs, Default: 4

Value

dataframe with the following columns:

study_id: study identification
ae_per_visit_mean: mean AE per visit per study
site_number: site
max_visit_sd: standard deviation of maximum patient visits per site
max_visit_mean: mean of maximum patient visits per site
n_pat: number of patients

Examples


df_visit1 <- sim_test_data_study(n_pat = 100, n_sites = 10,
                                 frac_site_with_ur = 0.4, ur_rate = 0.6)

df_visit1$study_id <- "A"

df_visit2 <- sim_test_data_study(n_pat = 100, n_sites = 10,
                                 frac_site_with_ur = 0.2, ur_rate = 0.1)

df_visit2$study_id <- "B"

df_visit <- dplyr::bind_rows(df_visit1, df_visit2)

df_site_max <- df_visit %>%
  dplyr::group_by(study_id, site_number, patnum) %>%
  dplyr::summarise(max_visit = max(visit),
            max_ae = max(n_ae),
            .groups = "drop")

df_config <- get_config(df_site_max)
