dst01.Rd

The DST01 Disposition Table provides an overview of patients study completion. For patients who discontinued the study a reason is provided.

Usage 

dst01_main(
  adam_db,
  arm_var = "ARM",
  lbl_overall = "All {Patient_label}",
  study_status_var = "EOSSTT",
  detail_vars = list(Discontinued = c("DCSREAS")),
  trt_status_var = NULL,
  ...
)

dst01_pre(adam_db, ...)

dst01_post(tlg, prune_0 = TRUE, ...)

dst01

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) variable. Usually one of ARM, ACTARM, TRT01A, or TRT01A.

lbl_overall

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

study_status_var

(string) variable used to define patient status. Default is EOSSTT, however can also be a variable name with the pattern EOPxxSTT where xx must be substituted by 2 digits referring to the analysis period.

detail_vars

Named (list) of grouped display of study_status_var. The names must be subset of unique levels of study_status_var.

trt_status_var

(string) variable of treatment status.

...

not used.

tlg

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

prune_0

(flag) remove 0 count rows

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).

Details

  • Default patient disposition table summarizing the reasons for patients withdrawal.

  • Numbers represent absolute numbers of patients and fraction of N.

  • Remove zero-count rows.

  • Split columns by arm.

  • Include a total column by default.

  • Sort withdrawal reasons by alphabetic order.

Functions

  • dst01_main(): Main TLG function

  • dst01_pre(): Preprocessing

  • dst01_post(): Postprocessing

Note

  • adam_db object must contain an adsl table with the columns specified by status_var and disc_reason_var.
