aet05_main: AET05 Table 1 (Default) Adverse Event Rate Adjusted for Patient-Years at Risk - First Occurrence.

Description

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

Usage

aet05_main(
  adam_db,
  dataset = "adsaftte",
  arm_var = "ACTARM",
  lbl_overall = NULL,
  ...
)
aet05_pre(adam_db, dataset = "adsaftte", ...)
aet05_post(tlg, prune_0 = FALSE, ...)
aet05

Value

the main function returns an rtables object.

the preprocessing function returns a list of data.frame.

the postprocessing function returns an rtables object or an ElementaryTable (null report).

Format

An object of class chevron_t of length 1.

Arguments

adam_db

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

dataset

(string) the name of a table in the adam_db object.

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

Functions

• aet05_main(): Main TLG function

• aet05_pre(): Preprocessing

• aet05_post(): Postprocessing

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.

Examples

library(dplyr)
library(dunlin)

proc_data <- log_filter(syn_data, PARAMCD == "AETTE1", "adsaftte")

run(aet05, proc_data)

run(aet05, proc_data, conf_level = 0.90, conf_type = "exact")
