DST01 Table 2 (Supplementary) Patient Disposition Table 2.

The DST01_2 Disposition Table provides an overview of patients study completion. For patients who discontinued the study, the reason provided is categorized as "Safety" or "Non-Safety" issue.

Usage

dst01_2_main(
  adam_db,
  arm_var = "ARM",
  status_var = "EOSSTT",
  disc_reason_var = "DCSREAS",
  lbl_overall = "All Patients",
  deco = std_deco("DST01"),
  ...
)

dst01_2_lyt(
  arm_var,
  status_var,
  disc_reason_var,
  completed_lbl,
  ongoing_lbl,
  discontinued_lbl,
  lbl_overall,
  deco = std_deco("DST01")
)

dst01_2_pre(adam_db, status_var = "EOSSTT", disc_reason_var = "DCSREAS", ...)

dst01_2_post(tlg, prune_0 = TRUE, deco = std_deco("DST01"), ...)

dst01_2

Format

An object of class chevron_t of length 1.

Arguments

adam_db: (dm) object containing the ADaM datasets
arm_var: (character) variable used for column splitting
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.
disc_reason_var: (string) variable used to define reason for patient withdrawal. Default is DCSREAS, however can also be a variable with the pattern DCPxxRS where xx must be substituted by 2 digits referring to the analysis period.
lbl_overall: (character) label used for overall column, if set to NULL the overall column is omitted
deco: (character) decoration with title, subtitles and main_footer content
...: not used.
completed_lbl: (string) associated with completed study and found in the columns given by status. By Default COMPLETED.
ongoing_lbl: (string) associated with ongoing treatment and found in the columns given by status_treatment. By Default `ONGOING.
discontinued_lbl: (string) associated with discontinued study and found in the columns given by status. By Default DISCONTINUED.
tlg: (TableTree, Listing or ggplot) object typically produced by a main function.
prune_0: (logical) remove 0 count rows

Details

Non-standard disposition table summarizing the reasons for patient withdrawal.
Withdrawal reasons are grouped into Safety and Non-Safety issues.
Safety issues include Death and Adverse events.
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.

Since the two parts of the tables are pruned differently, the layout function returns a list of layouts, which allows the tables to be constructed and pruned separately before binding.

Functions

dst01_2_main(): Main TLG function
dst01_2_lyt(): Layout
dst01_2_pre(): Preprocessing
dst01_2_post(): Postprocessing

Note

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