This is a simulated dataset used to illustrate Bayesian dynamic borrowing in the case when borrowing from an external control arm with a time-to-event endpoint, where the baseline covariate distributions of the internal and external data are balanced via inverse probability weighting.

int_tte_df

A data frame with 160 rows and 10 columns:

subjid

Unique subject ID

y

Response (observed time at which the participant either had an event or was censored)

enr_time

Enrollment time

total_time

Time from study start

event

Event indicator (1: event; 0: censored)

trt

Treatment indicator, where 0 = control and 1 = active treatment

cov1

Covariate 1, which is normally distributed around 62 with a SD of 8

cov2

Covariate 2, which is binary (0 vs. 1) with about 40% of participants having level 1

cov3

Covariate 3, which is binary (0 vs. 1) with about 40% of participants having level 1

cov4

Covariate 4, which is binary (0 vs. 1) with about 60% of participants having level 1
