A simulated data set of 200 patients in a two-arm chemotherapy trial. The column names, types and label attributes match gtsummary::trial, so gtsummary examples can be run unchanged; the values themselves are different. Generated with a fixed seed in data-raw/trial.R.

Usage

trial

Format

A data frame with 200 rows and 8 variables:

trt

Chemotherapy Treatment: "Drug A" or "Drug B"

age

Age, years (11 missing)

marker

Marker Level (ng/mL) (10 missing)

stage

T Stage: factor with levels T1, T2, T3, T4

grade

Grade: factor with levels I, II, III

response

Tumor Response: 1 = responder, 0 = non-responder (7 missing)

death

Patient Died: 1 = died within 24 months, 0 = censored

ttdeath

Months to Death/Censor, administratively censored at 24

Source

Simulated; no real patients. See data-raw/trial.R.
