The AET05 table produces the standard adverse event rate adjusted for patient-years at risk summary considering first occurrence.

Usage

aet05_main(adam_db, arm_var = "ACTARM", lbl_overall = NULL, ...)

aet05_pre(adam_db, ...)

aet05_post(tlg, prune_0 = FALSE, ...)

aet05

Format

An object of class chevron_t of length 1.

Arguments

adam_db

(list of data.frames) object containing the ADaM datasets

arm_var

(string) the arm variable used for arm splitting.

lbl_overall

(string) label used for overall column, if set to NULL the overall column is omitted

...

Further arguments passed to tern::control_incidence_rate().

tlg

(TableTree, Listing or ggplot) object typically produced by a main function.

prune_0

(flag) remove 0 count rows

Details

  • Total patient-years at risk is the sum over all patients of the time intervals (in years).

  • Split columns by arm, typically ACTARM.

  • Split rows by parameter code.

  • AVAL is patient-years at risk.

  • n_events is the number of adverse events observed.

  • The table allows confidence level to be adjusted, default is 95%.

  • Keep zero count rows by default.

Functions

  • aet05_main(): Main TLG function

  • aet05_pre(): Preprocessing

  • aet05_post(): Postprocessing

Note

  • adam_db object must contain an adaette table with the columns "PARAMCD", "PARAM", "AVAL", and "CNSR".
