Here is only a minimal example:
library(forestly)
forestly_adsl$TRTA <- factor(forestly_adsl$TRT01A, levels = c("Xanomeline Low Dose", "Placebo"), labels = c("Low Dose", "Placebo"))
forestly_adae$TRTA <- factor(forestly_adae$TRTA, levels = c("Xanomeline Low Dose", "Placebo"), labels = c("Low Dose", "Placebo"))
meta_forestly(
dataset_adsl = forestly_adsl,
dataset_adae = forestly_adae,
population_subset = SAFFL == "Y",
observation_subset = SAFFL == "Y"
) |>
