Load Example Clinical Trial Data

Returns one of five small, made-up tables from a simulated clinical trial of 48 subjects: demographics, exposure (dosing), lab results, adverse events or vital signs. Set cutoff_date to get the data as it stood on that date, which mimics a new data delivery each month; datom_example_cutoffs() lists the dates the examples use.

Usage

datom_example_data(
  domain = c("dm", "ex", "lb", "ae", "vs"),
  cutoff_date = NULL
)

Arguments

domain

One of "dm" (demographics, 48 rows), "ex" (exposure, 48 rows), "lb" (labs, 720 rows: 3 visits x 5 tests per subject), "ae" (adverse events, ~80 rows), or "vs" (vital signs, 432 rows: 3 visits x 3 tests per subject, taken on the same dates as the labs).

cutoff_date

Optional date string ("YYYY-MM-DD") to filter rows whose primary date column is on or before this date, simulating a point-in-time EDC extract. The date column used per domain: RFSTDTC (dm), EXSTDTC (ex), LBDTC (lb), AESTDTC (ae), VSDTC (vs).

Value

A data frame.

Details

The data simulates STUDY-001, a Phase II study enrolling over six months; table and column names loosely follow SDTM.

Examples

# Full demographics
dm <- datom_example_data("dm")

# Month-3 snapshot (subjects enrolled by 2026-03-28)
dm_m3 <- datom_example_data("dm", cutoff_date = "2026-03-28")

# Labs collected through Month 3
lb_m3 <- datom_example_data("lb", cutoff_date = "2026-03-28")
