Tech stack: r
Domain: data-visualization

Research direction

Start by running the supplied R example through the ae_forestly() entry point with the longer treatment labels, then inspect the forest-plot rendering path. Confirm the gray line appears with those labels and verify that the completed change removes it without changing the intended labels or plot output.

Written by the indexing model from the issue text.

Description

See a grey line generated when using longer labels for treatment arms:

adsl <- forestly_adsl
adae <- forestly_adae

adsl$TRTA <- factor(forestly_adsl$TRT01A,
                    levels = c("Xanomeline Low Dose", "Placebo"),
                    labels = c("Low Dose   long label", "Placebo   long label")
)
adae$TRTA <- factor(forestly_adae$TRTA,
                    levels = c("Xanomeline Low Dose", "Placebo"),
                    labels = c("Low Dose   long label", "Placebo   long label")
)

meta <- meta_adam(population = adsl, observation = adae) |>
  define_plan(plan = plan(
    analysis = "ae_forestly",
    population = "apat",
    observation = "apat",
    parameter = "any;drug-related"
